Congruency, Homomorphism  and Isomorphism on Autometrized Algebras [version 2; peer review: 2 approved, 1 approved with reservations] [PDF]

F1000Research
This paper presents a study of congruence relations on autometrized algebras. We demonstrate that in a normal autometrized algebra, which satisfies certain conditions, the set of all congruence relations forms a complete sublattice within the set of all ...

Linear regressive weighted Gaussian kernel liquid neural network for brain tumor disease prediction using time series data [PDF]

Scientific Reports
A brain tumor is an abnormal growth of cells within the brain or surrounding tissues, which can be either benign or malignant. Brain tumors develop in various regions of the brain, each affecting different functions such as movement, speech, and vision ...

On Quasi-P-Almost Distributive Lattices

Discussiones Mathematicae - General Algebra and Applications, 2020
In this paper, the concept of quasi pseudo-complementation on an Almost Distributive Lattice (ADL) as a generalization of pseudo-complementation on an ADL is introduced and its properties are studied.

Fuzzy Ideals and Fuzzy Filters of Pseudocomplemented Semilattices

Advances in Fuzzy Systems, 2019
In this paper, we introduce the concept of kernel fuzzy ideals and ⁎-fuzzy filters of a pseudocomplemented semilattice and investigate some of their properties.

Counting surface-kernel epimorphisms from a co-compact Fuchsian group to a cyclic group with motivations from string theory and QFT

Nuclear Physics B, 2016
Graphs embedded into surfaces have many important applications, in particular, in combinatorics, geometry, and physics. For example, ribbon graphs and their counting is of great interest in string theory and quantum field theory (QFT).

On QI-Algebras

Discussiones Mathematicae - General Algebra and Applications, 2017
In this paper, the notion of a QI-algebra is introduced which is a generalization of a BI-algebra and there are studied its properties. We considered ideals, congruence kernels in a QI-algebra and characterized congruence kernels whenever a QI-algebra is

Open Filters and Congruence Relations on Self-Distributive Weak Heyting Algebras

Bulletin of the Section of Logic
In this paper, we study (open) filters and deductive systems of self-distributive weak Heyting algebras (SDWH-algebras) and obtain some results which determine the relationship between them. We show that the variety of SDWH-algebras is not weakly regular

Strong endomorphism kernel property for finite Brouwerian semilattices and relative Stone algebras [PDF]

Mathematica Bohemica
We show that all finite Brouwerian semilattices have strong endomorphism kernel property (SEKP), give a new proof that all finite relative Stone algebras have SEKP and also fully characterize dual generalized Boolean algebras which possess SEKP.
