A Semi‐Discrete Lagrangian‐Eulerian Numerical Scheme for Diffusive‐Dispersive Conservation Laws With Discontinuous Coefficient

open access: yesNumerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT In this work, we present an extension of the semi‐discrete Lagrangian‐Eulerian numerical scheme for diffusive‐dispersive conservation law problems, including a jump discontinuous flux function. As in the one‐dimensional scalar hyperbolic case, the no‐flow curves also organize the geometry of the method.

Derivations as algebras

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract Differential categories provide the categorical foundations for the algebraic approaches to differentiation. They have been successful in formalizing various important concepts related to differentiation, such as, in particular, derivations. In this paper, we show that the differential modality of a differential category lifts to a monad on ...

On Leibniz-Poisson special polynomial identities

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
In this paper we study Leibniz-Poisson algebras satisfying polynomial identities. We study Leibniz-Poisson special and Leibniz-Poisson extended special polynomials.

FRIEZE PATTERNS WITH COEFFICIENTS

open access: yesForum of Mathematics, Sigma, 2020
Frieze patterns, as introduced by Coxeter in the 1970s, are closely related to cluster algebras without coefficients. A suitable generalization of frieze patterns, linked to cluster algebras with coefficients, has only briefly appeared in an unpublished ...

Multipliers and unicentral Leibniz algebras [PDF]

open access: yesJournal of Algebra and Its Applications, 2021
In this paper, we prove Leibniz analogues of results found in Peggy Batten’s 1993 dissertation. We first construct a Hochschild–Serre-type spectral sequence of low dimension, which is used to characterize the multiplier in terms of the second cohomology group with coefficients in the field.

Syntomic cohomology and real topological cyclic homology

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract We define motivic filtrations on real topological Hochschild homology and its companions. In particular, we prove that real topological cyclic homology admits a natural complete filtration whose graded pieces are equivariant suspensions of syntomic cohomology.

Reversal of economic integration: evidence from European Union enlargement

open access: yesThe Scandinavian Journal of Economics, Volume 128, Issue 3, Page 660-685, July 2026.
Abstract Empirical models of trade agreements implicitly assume that withdrawal from a trade agreement has an equal and opposite trade effect as accession (i.e., symmetry). With increasing opposition to international economic cooperation, it becomes urgent to test this assumption.

On an analogue of Schur's theorem for Leibniz $n$-algebras

open access: yesResearches in Mathematics
In this paper, we investigate relationships between certain important subalgebras of Leibniz $n$-algebras. In particular, we establish a close connection between the central factor-algebra of a Leibniz $n$-algebra and its derived ideal. As an application,

Methods of group theory in Leibniz algebras: some compelling results

open access: yesResearches in Mathematics, 2021
The theory of Leibniz algebras has been developing quite intensively. Most of the results on the structural features of Leibniz algebras were obtained for finite-dimensional algebras and many of them over fields of characteristic zero.

MINIMAL NONNILPOTENT LEIBNIZ ALGEBRAS

open access: yesInternational Electronic Journal of Algebra, 2020
We classify all nonnilpotent, solvable Leibniz algebras with the property that all proper subalgebras are nilpotent. This generalizes the work of Stitzinger and Towers in Lie algebras. We show several examples which illustrate the differences between the Lie and Leibniz results.
