-structure on Hochschild cohomology for exceptional local algebras of quaternion type. Case of the small parameter
Andrei V. Semenov
This is the second paper in the cycle of articles about -structure on Hochshild cohomology of exceptional algebras of quaternion type. We give -structure's full description…
On generating sets of infinite symmetric group
Andrei V. Semenov, Aleksandra Denisova
It was shown that in a group of bijections of an infinite set some families of subsets, related to the cardinality of some eigenspaces, are generating. Besides, we derived a criter…
Twisted forms of commutative monoid structures on affine spaces
Andrei V. Semenov, Pavel Gvozdevsky
In this paper, we study affine commutative algebraic monoid structures on affine spaces over an arbitrary field of characteristic zero. We obtain full classification of such struct…
-structure on Hochschild cohomology for exceptional local algebras of quaternion type. Case of even parameter
Alexander Generalov, Andrei V. Semenov
We give a full description of the -structure on the Hochschild cohomology of exceptional local algebras of quaternion type, defined by parameters in case of even para…
A Simple proof of Curtis' connectivity theorem for Lie powers
Sergei O. Ivanov, Vladislav Romanovskii, Andrei Semenov
We give a simple proof of the Curtis' theorem: if is -connected free simplicial abelian group, then is an -connected simp…
