Multiplicative derivations in $\vee$-hoop algebras [PDF]

open access: yesJournal of Mahani Mathematical Research
In this paper, first, while introducing multiplicative derivations, we examine some properties of these derivations and present properties of multiplicative derivations in $\vee$-hoop algebras. Then we show that the set of multiplicative derivations on $\

Identities in the Algebra of Partial Maps [PDF]

open access: yes, 2005
We consider the identities of a variety of semigroup-related algebras modelling the algebra of partial maps. We show that the identities are intimately related to a weak semigroup deductive system and we show that the equational theory is decidable.

DMA:an algebra for multicriteria spatial modeling [PDF]

open access: yes, 2006
The objective of this paper is to propose a new algebra, called decision map algebra (DMA), especially devoted to multicriteria spatial modeling. DMA is a generic and context-independent modeling language inspired from map algebra and other similar ...

Mathematics anxiety: Effects of age, gender and culture

open access: yesBritish Journal of Educational Psychology, Volume 96, Issue 2, Page 896-921, June 2026.
Abstract Background Many studies have indicated that mathematics anxiety is a significant problem for many people and is an important topic for research. Mathematics anxiety is multidimensional. In particular, it is important to distinguish between worry and emotionality components, and between trait and state anxiety.

Nilpotent subspaces of maximal dimension in semisimple Lie algebras [PDF]

open access: yes, 2006
We show that a linear subspace of a reductive Lie algebra g that consists of nilpotent elements has dimension at most equal to the number of positive roots, and that any nilpotent subspace attaining this upper bound is equal to the nilradical of a Borel ...
