斎藤義久 氏 (東大数理)
On the module category of ¥overline{U}_q(¥mathfrak{sl}_2) (JAPANESE)
[ 講演概要 ]
In the representation theory of quantum groups at roots of unity, it is
often assumed that the parameter q is a primitive n-th root of unity
where n is a odd prime number. However, there has recently been
increasing interest in the the cases where n is an even integer ---
for example, in the study of logarithmic conformal field theories, or in
knot invariants. In this talk,
we work out a fairly detailed study on the category of finite
dimensional
modules of the restricted quantum ¥overline{U}_q(¥mathfrak{sl}_2)
where
q is a 2p-th root of unity, p¥ge2.
