On commutativity in prime Γ-near-rings with symmetric bi-derivations
, 2014 In this paper, we investigate the conditions of a prime Γ-near-ring to be commutative by means of symmetric bi-derivations.

Musical Chemistry and Spectroscopy: Analogies Bridging Two Worlds in Multiple Dimensions
Helvetica Chimica Acta, Volume 109, Issue 9, September 2026.Music and spectroscopy speak the same language: that of fluctuations, line shapes, and ensembles. Herein, we establish useful analogies between music, chemistry, and spectroscopy, extending even to multidimensional and time‐resolved spectroscopies, with a mathematically‐grounded derivation and motivation.

The Commutativity of a *-Ring with Generalized Left *-α-Derivation
Advances in Pure Mathematics, 2018 In this paper, it is defined that left *-α-derivation, generalized left *-α-derivation and *-α-derivation, generalized *-α-derivation of a *-ring where α is a homomorphism. The results which proved for generalized left *-derivation of R in [1] are extended by using generalized left *-α-derivation. The commutativity of a *-ring with generalized left *-

Gamma (co)homology of commutative algebras and some related representations of the symmetric group [PDF]
This thesis covers two related subjects: homology of commutative algebras and certain representations of the symmetric group. There are several different formulations of commutative algebra homology, all of which are known to agree when one works over

Incidence Rings: Automorphisms and Derivations
, 2023 We study automorphisms, isomorphisms, and derivations of the incidence algebra $I(X,R)$, where $X$ is preordered set and $R$ is an algebra over some commutative ring $T$

Derivations of Skew Polynomial Rings [PDF]
, 1995 Let F be a field of characteristic 0 and let λi,j ∈ F. for 1 ≤ i,j ≤ n. Define R = F[x1,x2,..., xn] to be the skew polynomial ring with xixj = λi,jxjxi and let S = F[x1,x2,...,xn, x−11, x−12,...,x−1n] be the corresponding Laurent polynomial ring.

Aggregation and the Structure of Value
Noûs, Volume 60, Issue 3, Page 619-644, September 2026.ABSTRACT Roughly, the view I call “Additivism” sums up value across time and people. Given some standard assumptions, I show that Additivism follows from two principles. The first says that how lives align in time cannot, in itself, matter. The second says, roughly, that a world cannot be better unless it is better within some period or another.

On tested Bousfield–Friedlander localizations
Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.Abstract We show that a Bousfield–Friedlander localization of a model category of functors with respect to a set of test morphisms, as introduced by Bandklayder, Bergner, Griffiths, Johnson and Santhanam, can be characterized as a left Bousfield localization at a specific tensoring of the set of homotopy generators.

Lie Rings of (anti-)symmetric Derivations of Commutative Rings [PDF]
, 2013 [[abstract]]Let R be a 2-torsion free commutative ring with involution *, and δ a non-zero derivation of R. Let S be the set of symmetric elements in R and K the set of anti-symmetric elements in R.

Towards quantum hierarchy for the Gromov–Witten theory of elliptic curves
Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.Abstract We construct the quantum double ramification (DR) hierarchy associated with the Gromov–Witten theory of elliptic curves. We use results of Oberdieck and Pixton on the intersection numbers of the DR cycle, the Gromov–Witten classes of the elliptic curve, and the Hodge class λg−1$\lambda _{g-1}$, together with vanishing results for λg−2$\lambda ...
