DIMACS/DIMATIA/Renyi Working Group on Extremal Combinatorics Working Group Meetings: First Meeting Date: April 10 - 16, 2003 Location: Alfred Renyi Institute, Budapest, Hungary Second Meeting Date: TBD Location: TBD Third Meeting Date: TBD Location: TBD Organizers: Gyula Katona , Alfred Renyi Institute, ohkatona@renyi.hu Working Group Agenda: This working group will concentrate on two general topics, extremal graph theory and extremal problems arising from combinatorial search and testing. Extremal graph theory ([9, 34]) deals with graphs satisfying specified constraints and optimizing some criterion. We plan to investigate jointly a number of specific questions of current research interest in this field, which has played a fundamental role in the history of graph theory. In general, we shall be interested in . Here, a family L of sample graphs is fixed and we consider various conditions on a graph on n vertices that does not contain any graph in L as a subgraph (not necessarily induced). The most famous such problem asks for the maximum number of edges ext(n,L)

In 1944 he was forced to a Fascist Labour Camp but somehow managed to escape. He obtained false papers and hid for six months avoiding capture. During this time his parents were held prisoners in the Budapest ghetto. Alfréd rescued them with an extreme act of bravery:- Alfréd got hold of a soldier's uniform, walked into the ghetto, and marched his parents out. ... It requires familiarity with the circumstances to appreciate the skill and courage needed to perform these feats. At the end of World War II, Rényi obtained a Ph.D. at Szeged under F Riesz for work on Cauchy Fourier series. He was taught by Fejér at Budapest, then he went to Russia and worked with

Forum Chat Newsletter Nachrichten ... Suche Specials Eignungstest Kreditkarte The Strange Logic of Random Graphs (Algorithms and Combinatorics Vol. 22) von Joel Spencer Kategorie: Diskrete Mathematik ISBN: 3540416544 Kommentar abgeben Kurzbeschreibung The study of random graphs was begun by Paul Erdos and Alfred Renyi in the 1960s and now has a comprehensive literature. A compelling element has been the threshold function, a short range in which events rapidly move from almost certainly false to almost certainly true. This book now joins the study of random graphs (and other random discrete objects) with mathematical logic. The possible threshold phenomena are studied for all statements expressible in a given language. Often there is a zero-one law, that every statement holds with probability near zero or near one. The methodologies involve probability, discrete structures and logic, with an emphasis on discrete structures. The book will be of interest to graduate students and researchers in discrete mathematics.

"A matemetika olyan,mint a te Helené lányod, aki minden kérõjére gyanakszik, hogy az valójában nem is õt szereti, hanem csak azért udvarol neki, mert a király veje akar lenni. Õ olyan férjet akar, aki önmagáért, szépségéért, bájáért és sziporkázó szelleméért szereti õt, és nem azért a vagyonért és hatalomért, amit a királylány feleségül vételével szerezhet. Ha valaki minden apró lépés elõtt azt kérdezi: "Mi hasznom származik abból, ha ezen átrágom magam?", az nem fog messzire jutni a matematikában."

The Cook Book Recipe for the week of February 26 - March 3 Ultimate Bacon: The Giant Component of a Complex Network Let's take a break from our usual fare to discuss an amusing contest that I entered last weekend. Apparently, sometime within the past few years, MTV talk show host Jon Stewart devised a parlor game in which contestants are to link any movie star to Kevin Bacon by a chain of films that share performers. Thus we imagine actors as vertices in a large network, with edges between any two who have been in a movie together. The goal is to find the path of minimal length connecting x to Kevin Bacon, that length then being the Bacon number , which we denote here as B(x) . Quite a cult has grown up around this pastime, as witnessed by more than a dozen web pages now devoted to the game. Now Brett Tjaden and Glenn Wasson at the University of Virginia have automated the calculation of B(x) at their Web site, The Oracle of Bacon . Their program, which makes use of the marvelous Internet Movie Database (IMDB), will compute the Bacon number of any performer you care to specify within a few seconds. Hard-core cultists seem threatened by the power of the Oracle, but the rest of us welcome this automation of what can be an arduous evaluation. For instance
