'''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 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
