All Regular-Solid Varieties of Idempotent Semirings
Discussiones Mathematicae - General Algebra and Applications, 2017 The lattice of all regular-solid varieties of semirings splits in two complete sublattices: the sublattice of all idempotent regular-solid varieties of semirings and the sublattice of all normal regular-solid varieties of semirings.

CHIMIA, 1975 As colloidal manganese oxide hydroxides in natural waters occur in an infinity of finely divided varieties of an apparently limited number of (unknown) phases, an attempt has been made to prepare standard samples of the so-called “10 Å phase” which we ...

Cancellable Elements in the Lattice of Overcommutative Semigroup Varieties [PDF]
, 2021 We completely determine all cancellable elements in the lattice OC of all overcommutative semigroup varieties. In particular, we prove that an overcommutative semigroup variety is a cancellable element of the lattice OC if and only if it is a neutral ...

A Logic for Dually Hemimorphic Semi-Heyting Algebras and its Axiomatic Extensions
Bulletin of the Section of Logic, 2022 The variety \(\mathbb{DHMSH}\) of dually hemimorphic semi-Heyting algebras was introduced in 2011 by the second author as an expansion of semi-Heyting algebras by a dual hemimorphism.

On the lattice of varieties of bands of groups [PDF]
Pacific Journal of Mathematics, 1980 1* Introduction* When considered as semigroups with an additional unary operation x —> x~\ where x~ denotes the (unique) inverse of x in the subgroup to which it belongs, the class CR of completely regular semigroups (often called unions of groups) forms a variety of universal algebras, containing as a subvariety thevariety BG of bands of groups (those

A large class of small varieties of lattice-ordered groups [PDF]
, 1975 We establish the existence of a countable collection of varieties, each of which covers the abelian variety in the lattice of varieties of lattice-ordered groups.
