DESCRIPTION:José Cantarero\, CIMAT\nIn this talk we will give a descripti
 on of the twisted K-theory of the p-completion of the classifying space o
 f a finite group\, and more generally\, for classifying spaces of p-local
  finite groups. We will begin by introducing representations of p-groups
  which are invariant under fusion\, some examples and a completion theore
 m relating them to the K-theory of a p-completed classifying space. After
  this\, we consider rings of twisted representations and an alternative i
 nterpretation of twisted K-theory. Both objects will be interpreted in te
 rms of central extensions of p-local finite groups\, allowing us to give 
 a completion theorem for twisted K-theory. This is joint work with Noe Ba
 rcenas.\n \nWe will end with some questions regarding the behaviour of fu
 sion-invariant representations.
