The Additive Logic of Epistemic Reasons: An Axiomatic Account
Theoria, EarlyView.ABSTRACT The article argues for a system of axioms that is meant to capture the logic of normative reasons for belief. The system concerns a primitive direct‐reason relation, a defined doxastic‐reason relation, and a primitive function for the revision of rational belief by reasons.

Finitely valued commutator sequences [PDF]
, 2017 If x and y are elements in the group G, then we denote their commutator by x o y = x-1y-1 = x-1xy; and x o G is the set of all commutators x o g with g G. A G-commutator sequence is a series of elements ci G with c1 + 1 ci O G. Slightly generalizing well

Symplectic commutator subgroups [PDF]
, 2007 This paper expands on the work of Douglas Costa and Gordon Keller. Costa and Keller used a structure called the commutator subgroup to find the normal subgroups of special linear groups and symplectic groups.

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 ...

Local multiplicativity of perverse filtrations
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract Let f:S→C$f:S\rightarrow C$ be a proper surjective morphism from a smooth Kähler surface to a smooth curve. We show that the local perverse filtration associated with the induced map S[n]→C(n)$S^{[n]}\rightarrow C^{(n)}$ is multiplicative on each fiber if and only if f$f$ is an elliptic fibration.

A Non-Commutative $n$-Nomial Formula
Rocky Mountain Journal of Mathematics, 2007 In this paper the author gives a general \(n\)-nomial expansion formula for \((x_1+\cdots+ x_n)^m\) in terms of degree \(m\) monomials in \(x_1,\dots, x_n\), under the assumption \(x_j x_i= p_{ij} x_i x_j\) for \(1\leq i< j\leq n\). This is a generalization of an early result independently given by \textit{M. P. Schützenberger} [C. R. Acad. Sci., Paris

Journal of Computational Chemistry, Volume 47, Issue 24, September 15, 2026.Quantum chemical methods of force field parameterization such as the Seminario method encountercompute limitations at large scales. We present a GNN framework that outperforms the Seminario method by 34% in reproducing infrared bond frequencies across prevalent functional groups, and is up to seven orders of magnitude faster on larger molecules ...
