A generalization of the topological Brauer group
نویسنده
چکیده
In the present paper we study some homotopy invariants which can be defined by means of bundles with fiber a matrix algebra. In particular, we introduce some generalization of the Brauer group in the topological context and show that any its element can be represented as a locally trivial bundle with the structure group N × k , k ∈ N . Finally, we discuss its possible applications in the twisted K-theory.

Topological Obstructions to Embedding a Matrix Algebra Bundle into a Trivial One
In the present paper we describe topological obstructions to embedding a (complex) matrix algebra bundle into a trivial one under some additional arithmetic condition on their dimensions. We explain a relation between this problem and some principal bundles with groupoid structure. Finally, we briefly discuss a relation to the Brauer group and its generalization.

متن کاملEquivariant Brauer groups and cohomology ✩
In this paper we present a cohomological description of the equivariant Brauer group relative to a Galois finite extension of fields endowed with the action of a group of operators. This description is a natural generalization of the classic Brauer–Hasse–Noether’s theorem, and it is established by means of a three-term exact sequence linking the relative equivariant Brauer group, the 2nd cohomo...
متن کاملTopological Methods for Complex-analytic Brauer Groups
Using methods from algebraic topology and group cohomology, I pursue Grothendieck’s question on equality of geometric and cohomological Brauer groups in the context of complex-analytic spaces. The main result is that equality holds under suitable assumptions on the fundamental group and the Pontrjagin dual of the second homotopy group. I apply this to Lie groups, Hopf manifolds, and complex-ana...
