'''Derived Azumaya Algebrais and Twisted K-theory'''
 
 
 
Topological K-theory of dg-categories is a localizing invariant of dg-categories over the complex numbers
 
taking values in the infinity category of KU-modules. In this talk I describe a relative version
 
of this construction; namely for X a quasi-compact, quasi-separated C-scheme I construct a
 
functor valued in the infinity category of sheaves of spectra on X(C), the complex points of X. For inputs
 
of the form Perf(X, A) where A is an Azumaya algebra over X, I characterize the values
 
of this functor in terms of the twisted topological K-theory of X(C). From this I deduce
 
a certain decomposition, for X a finite CW-complex equipped with a bundle P of projective
 
spaces over X, of KU(P) in terms of the twisted topological K-theory of X ; this is
 
a topological analogue of a result of Quillen’s on the algebraic K-theory of Severi-Brauer
 
schemes.
