 +  
−  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 Ktheory of <math> X(\mathbb{C}) </math>. From this I deduce

−  a certain decomposition, for <math> X </math> a finite CWcomplex 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 Ktheory of <math> X </math> ; this is
