CTK Exchange Front Page Movie shortcuts Personal info ... Recommend this site Peg Solitaire and Group Theory Peg Solitaire (also known as Hi-Q) has very simple rules. Pegs (red circles) are allowed to jump over adjacent (vertically or horizontally) pegs. The peg that has been jumped over is removed. So jumps are like captures in Checkers. The goal of a regular game is to remove all pegs but one. In central solitaire , the player starts with pegs filling all the holes, except for the central one. According to the game brochure (Milton Bradley Co., 1986), whoever succeeds in leaving the last peg in the center is a genius . Anyone who leaves a single peg elsewhere is an outstanding player. Figure 1 Not long ago, with the help of very elementary group theory, Arie Bialostocki from University of Idaho proved that there are only five locations (b. above) where one can leave that single peg. Assuming that, e.g., that the peg was left in the rightmost hole, part c. in Figure 1 shows the position before the last move. The irony is in that from the same position the player can leave the sole remaining peg in the central hole, thus gaining the status of genius, instead of an outstanding player. Would one trade the distinction? It's this amazing observation that led Arie Bialostocki to developing his nice theory which I am going to outline below.

Abstract. The present series of articles by Michael Leyton, of which this is the first, will give an introduction to a comprehensive theory of design based on group theory in an intuitive form, and build up any needed group theory through tutorial passages. The articles will begin by assuming that the reader has no knowledge of group theory, and we will progressively add more and more group theory in an easy form, until we finally are able to get to quite difficult topics in tensor algebras, and give a group-theoretic analysis of complex buildings such as those of Peter Eisenman, Zaha Hadid, Frank Gehry, Coop Himmelblau, Rem Koolhaas, Daniel Libeskind, Greg Lynn, and Bernard Tschumi. This first article is on a subject of considerable psychological relevance: nested symmetries.

General Description of the Unit Groups are one of the main building blocks in mathematics. They form the basis of all rings, fields and vector spaces, and many objects studied in analysis and topology have a group-theoretic structure. Also, physicists use groups to describe properties of the fundamental particles of matter. Pure mathematicians use them to study symmetry properties of geometric figures, in problems concerning permutations, to classify sets of objects like points of algebraic curves, and to study collections of matrices as well as in many other uses. The unit will cover the basic parts of the subject and study finite groups in some detail. Relation to Other Units This unit develops the Group Theory material in Level 1 Pure Mathematics.

A History of GroupTheory William Komp History of Mathematics Dr. Davitt This raises the question of traits do all groups have in common, and as an extension on to this what additional traits do all fields share. There have been many interpretations of the structure of groups. H. Weber's notion of a group has for axioms, but it turns out that one of his axioms is unnecessary when compared to the modern definition. The modern definition of a group is as follows: Given any set A, we say that A forms a groupunder the binary operation @ if and only if it satisfies the followingfour criteria. I) Given any two elements in A, then their product under the binary operation @ will be in A [closure property] II) Given three elements in A, these three elements will satisfy the associative property. III) In A, there exists an element such thatthe product of this element with any other element in A, namely ©,will generate the element © back again. IV) There exists an element ©' in A suchthat the product of © and ©' will give the element mentionedin III.(Gallian) Group Theory has enormous potential in practical applications in areas other than that of mathematics. In mathematics, group theory is the basis of real analysis. Namely,the set of R, the real numbers, must be complete and satisfy all of theproperties of an ordered field (Sherwood 14-19). This provides thenecessary algebra to begin proving and developing axiomatically all ofCalculus. The analogy can also be made with the complex numbers,with some increased complexity in the area of complex analysis. The propertiesof a field are very similar to those of a group.

Group Theory of Wallpaper Patterns, an Epilogue Back to the lobby of the Mathematics Museum Back to the beginning of the group theory Why do only seventeen cases of symmetry occur in the previous table? Perhaps, you can understand the basic reason using the lemma below. Lemma Under the assumption of the conditions (1) and (2), G contains only rotations of 60, 90, 120 or 180 degrees. a translation parallel to the axis of the reflection for every reflection. Thus, every axis of a reflection is also an axis of a glide reflection. a translation perpendicular to the axis of the reflection or the glide reflection for every reflection and for every glide reflection. To understand wallpaper groups, we recommend you to demonstrate the figures of each of the seventeen pattern types for each of the following: (1) all axes of reflections, (2) all axes of glide reflections, and (3) all centers of rotations for each value of angles 60, 90, 120, and 180 degrees. It may be hard to show all seventeen patterns, but it becomes interesting to find the unexpected axes of glide reflections and unexpected centers of rotations after confirming them for several cases. A long time ago, people may have noticed there were seventeen ways to repeat patterns. We have several opinions on when and by whom the first mathematical verification was given. One of the oldest was given by Ergraf Stepanovic Fedorov in 1891. It may be true that since then, we have had repeated re-discoveries.

Group Theory of Wallpaper Patterns Back to the lobby of Mathematics Museum Consider a plane. Move it and put it onto exactly the same plane. (We admit turning it over, but don't admit folding it.) We call such movement a transformation and the set of all such transformations of the plane is called a Euclidean group , which is denoted by E. Note that NOT moving the plane is a kind of movement and is a special transformation. We therefore give it its own name. We call it an identity transformation. Theorem Any element of the Euclidean group E is one of the following: the identity transformation a rotation about a point a translation a reflection on an axis line on the plane a glide reflection on an axis line on the plane Consider a line on the plane and fix it as the axis. The transformation such that turning over the plane by rotating it through 180 degrees about the axis is called a reflection on this line. We regard the line as a mirror, and it associates any point on the plane with the mirror image of that point. Intuitively, a reflection "flips" the plane across the axis. The transformation equivalent to performing a reflection on a line and a translation parallel to the same line after the reflection is called a glide reflection on this line.

74. Cmm Muted group theory. Summary Muted group theory is a critical theory becauseit is concerned with power and how it is used against people. http://oregonstate.edu/instruct/theory/mutedgrp.html

Muted Group Theory Summary: Muted Group Theory is a critical theory because it is concerned with power and how it is used against people. While critical theories can separate the powerful and the powerless any number of ways, this theory chooses to bifurcate the power spectrum into men and women. Muted Group Theory begins with the premise that language is culture bound, and because men have more power than women, men have more influence over the language, resulting in language with a male-bias. Men create the words and meaning for the culture, allowing expression of their ideas. Women, on the other hand, are left out of this meaning creation and left without a means to express that which is unique to them. That leaves women as a muted group. The Muted Group Theory rests on three assumptions: Men and women perceive the world differently because they have different perception shaping experiences. Those different experiences are a result of men and women performing different tasks in society. Men enact their power politically, perpetuating their power and suppressing women's ideas and meanings from gaining public acceptance.

75. Group Theory But the authors also give an introduction to group theory, making use ofthe physical applications to illustrate and show how the theory works. http://www2.physics.umd.edu/~yskim/home/groth.html

Group Theoretical Approach to Physics The most familiar group in physics is the rotation group governing rotations in three-dimensional space. These rotations are norm-preserving transformations. This concept is then extended to unitary groups governing unitary transformations in quantum mechanics. These groups are also well known. I have been and still am interested in transformations which will transform a circle into ellipse, a square into a rectangle, and a sphere into an ellipsoid. It is quite natural to call these squeeze transformations. You will be surprised to hear that Lorentz boosts are squeeze transformations, as illustrated in the following figure. Have you seen this picture? This picture came from a paper which I published with M. E. Noz and S. H. Oh, in J. of Math. Phys. in 1979 (Vol. 20, page 1341). For an earlier version of this figure telling the same physics, see Y. S. Kim and M. E. Noz, Phys. Rev. D/8, 3521 (1973). The picture tells you that Lorentz boosts are squeeze transformations. It is often more convincing to explain what I did in terms of what others say about what I did.

While that sounds a bit esoteric (and it certainly can be), what it means is that it looks at the ways you can turn, rotate, or stretch one pattern or do-hickey back onto itself - which is something that puzzles like the Rubik's Cube and pictures like the ones Escher drew have in common. This course is an introduction to group theory using various puzzles as examples to make the subject more accessible and concrete. The level will depend on who shows up: at one extreme, some of us can taste the edges of a very beautiful piece of mathematics while learning to solve the Rubik's cube, while at the other extreme, some of us may delve into some deep mathematical proofs. We'll see where we want to head, and how far, depending on your backgrounds and interests. After our initial discussions, it now seems that folks doing the 2 credit version need only come on Thursdays, when we will focus on the puzzles and general ideas, while those who want to see more of the proofs and deeper mathematics should come Mondays as well, for the 3 credit version.
