DESCRIPTION:Tensor categories\, on the one hand\, are natural generalizati
ons of Hopf algebras\, and on the other hand\, they give us a very conveni
ent language both in representation theory and in mathematical physics. Fo
r example\, many algebraic aspects of two-dimensional conformal field theo
ries can be formulated in the language of tensor categories. I am interest
ed in the problem of deformation of such categories and will talk about ne
w results in this direction. As it is often in algebra\, infinitesimal def
ormations are controlled by Hochschild type complexes. I will show how to
use such complexes in rather explicit calculations of deformations of tens
or categories and tensor functors arising in Hopf algebra theory.\n\nOrate

iversité de Tours et Fachbereich Mathematik der Universität Hamburg)\nTe
nsor categories\, on the one hand\, are natural generalizations of Hopf al
gebras\, and on the other hand\, they give us a very convenient language b
oth in representation theory and in mathematical physics. For example\, ma
ny algebraic aspects of two-dimensional conformal field theories can be fo
rmulated in the language of tensor categories. I am interested in the prob
lem of deformation of such categories and will talk about new results in t
his direction. As it is often in algebra\, infinitesimal deformations are
controlled by Hochschild type complexes. I will show how to use such compl
