Morita bundle gerbes
Andrei V. Ershov
The aim of this paper is to give a survey of the theory of bundle gerbes. In our approach we especially emphasize the unifying role of Morita equivalences in this theory. We also d…
A bordism theory related to matrix Grassmannians
A. V. Ershov
In the present paper we study a bordism theory related to pairs where is a closed smooth oriented manifold with a stably trivial normal bundle and is a virtual…
A model of the twisted -theory related to bundles of finite order
A. V. Ershov
In the present paper we propose a geometric model of the twisted K-theory corresponding to elements of finite order in $H^3(X, \mathbb{Z})\times [X, \BBSU_\otimes]$.
On -theory automorphisms related to bundles of finite order
A. V. Ershov
In the present paper we describe the action of (not necessarily line) bundles of finite order on the -functor in terms of classifying spaces. This description might provide with…

Topological obstructions to embedding of a matrix algebra bundle into a trivial one
A. V. Ershov
In the present paper we describe topological obstructions to embedding of a (complex) matrix algebra bundle into a trivial one under some additional arithmetic condition on their d…
