__Inequalities related to free entropy derived from random matrix approximation__, (with F. Hiai and D. Petz)

Unpublished preprint. (2003). This is divided into [11,13] in the above list. [math.OA/0310453]

__Free Talagrand Inequality__, pdf.

Oberwolfach Reports No.15/2005, "Free Probability Theory", 857--861.

Summary mainly on the joint work with Fumio Hiai [14].

__On orbital free entropy dimension__, pdf.

This is an outtake of one of my private notes for the proceedings of the RIMS conference, Sep. 07.

We give a direct proof to the general upper bound of orbital free entropy dimension.

__Quick review on property (X)__, pdf.

This is an outtake of my private notes for the proceedings of the RIMS conference, Jun. 08.

We give a short survey on some techniques that are useful for proving the uniqueness of preduals.

__Free product factor and bicentralizer problem__, pdf.

This is originally a preprint circulated to restricted persons.

We confirmed that any type III$_1$ free product factor has the trivial asymptotic bicentralizer.

Only the Connes--Stormer transitivity and two results in [22] are used there. After that, Cyril Houdayer found that his technology gives a much simpler proof, which is included in [32].
