Hidden commutativity in semi-FTvN systems
A semi-FTvN system (short for semi-Fan-Theobald-von Neumann system) is a triple $(\mathcal{V},\mathcal{W},\lambda)$, where $\mathcal{V}$ and $\mathcal{W}$ are real inner product spaces and the mapping $\lambda:\mathcal{V}\rightarrow \mathcal{W ...

On commutativity of projectors [PDF]
, 2008 It is shown that commutativity of two oblique projectors is equivalent with their product idempotency if both projectors are not necessarily Hermitian but orthogonal with respect to the same inner ...

Certain Issues With the Commutativity of the Connective “i”
Studia Semiotyczne, 2020 DOI: http://doi.org/10.26333/stsen.xxxi.05 The conjunctive “i” is one of the four interpretations of the Polish connective “i” (“and” in English), along with the accessory, sequential and explicatory ones, which are distinguished by Olgierd ...

On the additive image of zeroth persistent homology
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract For a category X$X$ and a finite field F$F$, we study the additive image of the functor H0(−;F)∗:rep(X,Top)→rep(X,VectF)$\operatorname{H}_0(-;F)_* \colon \operatorname{rep}(X, \mathbf {Top}) \rightarrow \operatorname{rep}(X, \mathbf {Vect}_F)$, or equivalently, of the free functor rep(X,Set)→rep(X,VectF)$\operatorname{rep}(X, \mathbf {Set ...

Rational points on even‐dimensional Fermat cubics
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

Polyadic Systems, Representations and Quantum Groups
East European Journal of Physics, 2012 A review of polyadic systems and their representations is given. The classification of general polyadic systems is done. The multiplace generalization of homomorphisms, preserving associativity, is presented.

Strong commutativity preserving derivations on Lie ideals of prime Γ-rings [PDF]
Mathematica Moravica, 2019 Let M be a Γ-ring and S ⊆ M. A mapping f : M → M is called strong commutativity preserving on S if [f(x), f(y)]α = [x, y]α, for all x, y ∈ S, α ∈ Γ. In the present paper, we investigate the commutativity of the prime Γ-ring M of characteristic not 2 with

On the automorphisms of the power semigroups of a numerical semigroup
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract If H$H$ is a numerical semigroup (i.e., a cofinite subset of the non‐negative integers closed under addition), then the collection of all non‐empty subsets of H$H$ forms a semigroup P(H)$\mathcal {P}(H)$ under the sumset operation induced by addition in H$H$.

Semantics Based Commutativity Analysis of Object Methods
, 2005 Traditional analysis and usage of operation commutativity relies on pairwise commutativity relationships. In contrast, this paper presents method group commutativity, which specifies the conditions under which operations in a method group will commute ...

Minimal Freeness and Commutativity
, 1992 A pseudobasis for an abstract algebra A is a subset X of A such that every mapping X into A extends uniquely to an endomorphism on A. A is minimally free if A has a pseudobasis. In this paper we look at how minimal freeness interacts with various notions
