Regular S-acts with primitive normal and antiadditive theories
A. A. Stepanova, G. I. Baturin
In this work, we investigate the commutative monoids over which the axiomatizable class of regular S-acts is primitive normal and antiadditive. We prove that the primitive normalit…

Abelian and Hamiltonian groupoids
A. A. Stepanova, N. V. Trikashnaya
In the work we investigate some groupoids which are the Abelian algebras and the Hamiltonian algebras. An algebra is Abelian if for every polynomial operation and for all elements…
