| − | 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
