On Severi varieties as intersections of a minimum number of quadrics
Cubo, 2022 Let $\cV$ be a variety related to the second row of the Freudenthal-Tits Magic square in $N$-dimensional projective space over an arbitrary field. We show that there exist $M\leq N$ quadrics intersecting precisely in $\cV$ if and only if there exists a ...

Quantum Theory without the Axiom of Choice, and Lefschetz Quantum Physics
Physics, 2023 In this paper, we discuss quantum formalisms that do not use the axiom of choice. We also consider the fundamental problem that addresses the (in)correctness of having the complex numbers as the base field for Hilbert spaces in the København ...

A question of Frohardt on $2$ -groups, skew translation quadrangles of even order and cyclic STGQs
Forum of Mathematics, Sigma, 2023 We solve a fundamental question posed in Frohardt’s 1988 paper [6] on finite $2$ -groups with Kantor familes, by showing that finite groups K with a Kantor family $(\mathcal {F},\mathcal {F}^*)$ having distinct members $A, B \in \mathcal

m-Polar Fuzzy B-ideal of B-algebra
Cauchy: Jurnal Matematika Murni dan Aplikasi, 2023 B-algebra is an algebraic structure related to BCI/BCK-algebra. Many researchers have studied fuzzy B-ideal on B-algebra, m-polar fuzzy set on BCI-algebra and B-algebra, m-polar fuzzy subalgebra on BCI-algebra and B-algebra, m-polar fuzzy ideal on BCI ...

On the derivations of cyclic Leibniz algebras
Karpatsʹkì Matematičnì Publìkacìï, 2022 Let $L$ be an algebra over a field $F$. Then $L$ is called a left Leibniz algebra, if its multiplication operation $[-,-]$ additionally satisfies the so-called left Leibniz identity: $[[a,b],c]=[a,[b,c]]-[b,[a,c]]$ for all elements $a,b,c\in L$. A linear

On the derivations of Leibniz algebras of low dimension
Доповiдi Нацiональної академiї наук України, 2023 Let L be an algebra over a field F. Then L is called a left Leibniz algebra if its multiplication operations [×, ×] addition- ally satisfy the so-called left Leibniz identity: [[a,b],c] = [a,[b,c]] – [b,[a,c]] for all elements a, b, c Î L. In this paper,

QM-BZ-Algebras and Quasi-Hyper BZ-Algebras
Axioms, 2022 BZ-algebra, as the common generalization of BCI-algebra and BCC-algebra, is a kind of important logic algebra. Herein, the new concepts of QM-BZ-algebra and quasi-hyper BZ-algebra are proposed and their structures and constructions are studied.

Fixed Point Theorems for Noncyclic Monotone Relatively ρ-Nonexpansive Mappings in Modular Spaces
International Journal of Mathematics and Mathematical Sciences, 2020 In this paper, we obtain some fixed point results for noncyclic monotone ρ-nonexpansive mappings in uniformly convex modular spaces and uniformly convex in every direction modular spaces.

Quadratic BH-algebras and Quadratic TM-algebras
Tikrit Journal of Pure Science, 2023 In this paper we present the notion of “quadratic” BH-algebra and TM-algebra, and show that every quadratic BH-algebra and TM-algebra has a product of the form , where ; if is a field with and BCI-algebra.
