'''Derived Azumaya Algebras 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 <math> \infty </math>-category of  <math> KU </math>-modules. In this talk I describe a relative version
+
of this construction; namely for <math>X</math> a quasi-compact, quasi-separated <math> \mathbb{C} </math>-scheme I construct a
+
functor valued in the <math> \infty </math>-category of sheaves of spectra on <math> X(\mathbb{C}) </math>, the complex points of <math>X</math>. For inputs
+
of the form <math>\operatorname{Perf}(X, A)</math> where <math>A</math> is an Azumaya algebra over <math>X</math>, I characterize the values
+
of this functor in terms of the twisted topological K-theory of <math> X(\mathbb{C}) </math>. From this I deduce
+
a certain decomposition, for <math> X </math> a finite CW-complex equipped with a bundle <math> P </math> of projective
+
spaces over <math> X </math>, of <math> KU(P) </math> in terms of the twisted topological K-theory of <math> X </math> ; this is
+
a topological analogue of a result of Quillen’s on the algebraic K-theory of Severi-Brauer
+
schemes.
