Diaconescu, Moore, and Witten have pointed out that the twisted K-theory classification is not compatible with the S-duality covariance of type IIB string theory. For example, consider the constraint on the Ramond–Ramond 3-form field strength G3 in the Atiyah-Hirzebruch spectral sequence (AHSS): where d3=Sq +H is the first nontrivial differential in the AHSS, Sq is the third Steenrod square and … darmstadt psychotherapie https://mrrscientific.com

In mathematics, twisted K-theory (also called K-theory with local coefficients ) is a variation on K-theory, a mathematical theory from the 1950s that spans algebraic topology, abstract algebra and operator theory. More specifically, twisted K-theory with twist H is a particular variant of K-theory, in which the twist is … See more To motivate Rosenberg's geometric formulation of twisted K-theory, start from the Atiyah–Jänich theorem, stating that $${\displaystyle Fred({\mathcal {H}}),}$$ the Fredholm operators on Hilbert space See more Physicist typically want to calculate twisted K-theory using the Atiyah–Hirzebruch spectral sequence. The idea is that one begins with all of the even or all of the odd integral cohomology, depending on whether one wishes to calculate the twisted See more When $${\displaystyle H}$$ is the trivial class, twisted K-theory is just untwisted K-theory, which is a ring. However, when $${\displaystyle H}$$ is nontrivial this theory is no longer a ring. It has an addition, but it is no longer closed under multiplication.
