The Lyapin's notebook: a collection of unsolved problems in Semigroup Theory
S. Bershadsky, S. Kublanovsky, G. Mashevitzky
This collection presents a selected set of unsolved problems in semigroup theory, a fundamental branch of modern algebra. The publication is dedicated to the 110th anniversary of t…
Cyclically regular semigroups
Stanislav Kublanovsky
We study varieties of semigroups related to completely 0-simple semigroup. We present here an algorithmic descriptions of these varieties interms of "forbidden" semigroups.
On the Rees-Sushkevich variety
Stanislav Kublanovsky
We study varieties of semigroups related to completely 0-simple semigroup. We present here an algorithmic descriptions of these varieties in terms of "forbidden" semigroups. We als…
A minimal nonfinitely based semigroup whose variety is polynomially recognizable
Mikhail V. Volkov, Svetlana V. Goldberg, Stanislav I. Kublanovsky
We exhibit a 6-element semigroup that has no finite identity basis but nevertheless generates a variety whose finite membership problem admits a polynomial algorithm.
