'''Derived Azumaya Algebrais and Twisted K-theory'''
+
 
+
Topological K-theory of dg-categories is a localizing invariant of dg-categories over <math> \mathbb{C} </math>
+
taking values in the infinity category of  <math> KU </math>-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.
