Varieties of distributive rotational lattices [PDF]

, 2013
A rotational lattice is a structure (L;\vee,\wedge, g) where L=(L;\vee,\wedge) is a lattice and g is a lattice automorphism of finite order. We describe the subdirectly irreducible distributive rotational lattices.

Note on distributive posets [PDF]

, 2012
In this note we study distributive posets. We discuss several notions of distributivity in posets and show their equivalence. Moreover, the Prime Ideal Theorem for Distributive Posets is shown to be equivalent with the famous Prime Ideal Theorem for ...

Taxonomies of Model-theoretically Defined Topological Properties [PDF]

, 1990
A topological classification scheme consists of two ingredients: (1) an abstract class K of topological spaces; and (2) a taxonomy , i.e. a list of first order sentences, together with a way of assigning an abstract class of spaces to each sentence of ...

Congruences of Sheffer stroke basic algebras

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
In this paper, congruences and (order, prime and compatible) filters are introduced in Sheffer stroke basic algebras. They are interrelated with each other.

Integer partitions, tilings of $2D$-gons and lattices [PDF]

, 2002
In this paper, we study two kinds of combinatorial objects, generalized integer partitions and tilings of 2D-gons (hexagons, octagons, decagons, etc.).

Characterization of Almost Semi-Heyting Algebra

Discussiones Mathematicae - General Algebra and Applications, 2020
In this paper, we initiate the discourse on the properties that hold in an almost semi-Heyting algebra but not in an semi-Heyting almost distributive lattice.

Kleene algebras with implication [PDF]

, 2020
Inspired by an old construction due to J. Kalman that relates distributive lattices and centered Kleene algebras, in this paper we study an equivalence for certain categories whose objects are algebras with implication (H, ∧, ∨, →, 0, 1) which satisfy ...

Study of Hilbert algebras in point of filters

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
The aim of this work is to introduce some types of filters in Hilbert algebras. Some theorems are stated and proved which determine the relationship between these notions and other filters of Hilbert algebra and by some examples we show that these ...
