Twisted Morava K–theory and connective covers of Lie groups
نویسندگان
چکیده
Twisted Morava K-theory, along with computational techniques, including a universal coefficient theorem and an Atiyah-Hirzebruch spectral sequence, was introduced by Craig Westerland the first author. We employ these techniques to compute twisted K-theory of all connective covers stable orthogonal group unitary group, their classifying spaces, as well spheres Eilenberg-MacLane spaces. This extends case some results Ravenel Wilson Kitchloo, Laures, for K-theory. also generalizes chromatic levels computations Khorami (and in part those Douglas) at level one, i.e. establish that natural twists cases, there are only two possibilities: either homology vanishes, or it is isomorphic untwisted homology. provide variant on twist mod 2 cohomology place integral cohomology.

Twisted K–Theory of Lie Groups
I determine the twisted K–theory of all compact simply connected simple Lie groups. The computation reduces via the Freed–Hopkins–Teleman theorem [?] to the CFT prescription, and thus explains why it gives the correct result. Finally I analyze the exceptions noted by Bouwknegt et al [?].
متن کاملOn sheets of orbit covers for classical semisimple Lie groups
David Vogan gave programmatic conjectures about the Dixmier's map and he made two conjectures that induction may be independent of the choice of parabolic group used and the sheets of orbit data are conjugated or disjointed. In our previous paper, we gave a geometric version of the parabolic induction of the geometric orbit datum (i.e. orbit covers), and proved Vogan's rst conjecture for geomet...
متن کاملAlgorithmic problems in twisted groups of Lie type
This thesis contains a collection of algorithms for working with the twisted groups of Lie type known as Suzuki groups, and small and large Ree groups. The two main problems under consideration are constructive recognition and constructive membership testing. We also consider problems of generating and conjugating Sylow and maximal subgroups. The algorithms are motivated by, and form a part of,...
متن کاملOn the Twisted K-Homology of Simple Lie Groups
We prove that the twisted K-homology of a simply connected simple Lie group G of rank n is an exterior algebra on n − 1 generators tensor a cyclic group. We give a detailed description of the order of this cyclic group in terms of the dimensions of irreducible representations of G and show that the congruences determining this cyclic order lift along the twisted index map to relations in the tw...
متن کاملAverages over classical Lie groups, twisted by characters
We compute EG( ∏ i tr(g λi )), where g ∈G = Sp(2n) or SO(m) (m = 2n, 2n+1) with Haar measure. This was first obtained by Diaconis and Shahshahani [Persi Diaconis, Mehrdad Shahshahani, On the eigenvalues of random matrices, J. Appl. Probab. 31A (1994) 49–62. Studies in applied probability], but our proof is more self-contained and gives a combinatorial description for the answer. We also conside...
