Clones of Finite Idempotent Algebras with Strictly Simple Subalgebras
T Dent - 2011 - search.proquest.com
We determine the clone of a finite idempotent algebra [special characters omitted] that is not
simple and has a unique nontrivial subalgebra [special characters omitted] with more than …

Groupoids viewed as inverse semigroups
M Aukhadiev - arXiv preprint arXiv:1604.08585, 2016 - arxiv.org
A simple observation, showing that every groupoid becomes an inverse semigroup after
adding one element. In such inverse semigroups all idempotents are mutually orthogonal …

Semiring identities in the semigroup
VY Shaprynskiǐ - arXiv preprint arXiv:2305.17466, 2023 - arxiv.org
The semigroup $ B_0 $ is the only, up to isomorphism, 4-element subsemigroup of the 5-
element Brandt semigroup $ B_2 $. Being an inverse semigroup, the semigroup $ B_2 $ can …

Some classes of operator algebras generated by idempotents
H Ghahramani, B Fadaee - موجک و جبر خطی, 2022 - wala.vru.ac.ir
The algebra A is generated by idempotents if the generated algebra by its idempotents
equal to A. In this paper we show that if N is a finite nest on a complex Hilbert space H, then …

Searching for groups related to pseudo-composition algebras
VA Afanasev - arXiv preprint arXiv:2405.15900, 2024 - arxiv.org
We study the class of idempotent-generated pseudo-composition algebras, which is a
subclass of the family of axial algebras. More specifically, we utilise the group-algebra …

Subgroups of free idempotent generated semigroups: full linear monoid
M Brittenham, SW Margolis, J Meakin - arXiv preprint arXiv:1009.5683, 2010 - arxiv.org
We develop some new topological tools to study maximal subgroups of free idempotent
generated semigroups. As an application, we show that the rank 1 component of the free …
