DESCRIPTION:Quite generally\, a trace on a k-linear category is a family o
 f functions from the endomorphisms of objects to the underlying field k\, 
 subject to cyclicity and possibly other constraints. In some interesting c
 ases these functions may only exist for a subset of all objects. One situa
 tion where this may happen are non-semisimple braided finite tensor catego
 ries\, which have applications in link invariants and in two-dimensional c
 onformal field theory. In this talk I will present some results and conjec
 tures related to such categories.<span><br> <br> </span><br><br><br><br>
