0-Cohomology of semigroups
B. V. Novikov
This article is a survey of 0-cohomology of semigroups. The main attention is devoted to applications.
On decomposition of commutative Moufang groupoids
B. V. Novikov
We prove that every commutative Moufang groupoid is a semilattice of Archimedean subgroupoids.
Semigroup cohomology and applications
B. V. Novikov
This article is a survey of the author's research. It consists of three sections concerned three kinds of cohomologies of semigroups. Section 1 considers `classic' cohomology as it…
On quasi-Frobenius semigroup algebras
B. V. Novikov
We define quasi-Frobenius semigroups and find necessary and sufficient conditions under which a semigroup algebra of a 0-cancellative semigroup is quasi-Frobenius.
Finitary incidence algebras
N. S. Khripchenko, B. V. Novikov
We consider the functions in two variables on an arbitrary poset, for which the convolution operation is defined. We obtain the generalization of incidence algebra and describe its…
