Derivations of Group Algebras and Hochschild cohomology
A. S. Mishchenko
The Hochschild homology and cohomology group can be described in terms of the homology and cohomology of the classifying space of the groupoid of the adjoint action of the group un…
Smooth Version of Johnson's Problem Concerning Derivations of Group Algebras
A. A. Arutyunov, A. S. Mishchenko
A description of the algebra of outer derivations of a group algebra of a finitely presented discrete group is given in terms of the Cayley complex of the groupoid of the adjoint a…
Derivations of Group Algebras
A. A. Arutyunov, A. S. Mishchenko, A. I. Shtern
In the paper, a method of describing the outer derivations of the group algebra of a finitely presentable group is given. The description of derivations is given in terms of charac…
Some results on the Mackenzie obstruction for transitive Lie algebroids
Alexander S. Mishchenko, Leanh Nguyen
The preprint is prepared as description of results that were obtained during joint scientific project No: 71NC /2015/VNCCCT on the VIASM (Vietnam Institute for Advanced Study in Ma…
Description of coupling in the category of transitive Lie algebroids
Xiaoyu Li, Alexander S. Mishchenko
In our previous paper (arXiv:1306.5449) we have given a sufficient and necessary condition when the coupling between Lie algebra bundle (LAB) and the tangent bundle exists in the s…
The Existence of Coupling in the Category of Transitive Lie Algebroid
Xiaoyu Li, Alexander S. Mishchenko
The coupling of the tangent bundle with the Lie algebra bundle (K.Mackenzie,2005, Definition 7.2.2) plays the crucial role in the classification of the transitive Lie alge…
