Methods of group theory in Leibniz algebras: some compelling results
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.

Turán and Ramsey problems for alternating multilinear maps
Turán and Ramsey problems for alternating multilinear maps, Discrete Analysis 2023:12, 22 pp. Ramsey's theorem (in its finite version) states that for every positive integer $k$ there exists a positive integer $n$ such that every graph with $n$ vertices

Anomaly matching in the symmetry broken phase: Domain walls, CPT, and the Smith isomorphism
Symmetries in Quantum Field Theory may have 't Hooft anomalies. If the symmetry is unbroken in the vacuum, the anomaly implies a nontrivial low-energy limit, such as gapless modes or a topological field theory. If the symmetry is spontaneously broken,

Approximate invariance for ergodic actions of amenable groups
Approximate invariance for ergodic actions of amenable groups, Discrete Analysis 2019:6, 56 pp. A basic phenomenon in additive combinatorics is that the "size" of a sumset $A+B$ or product set $AB$ of two sets $A,B$ is "usually" at least as large as the

A result of Koranyi that describes the structure of the space of polynomial solutions to the Heisenberg Laplacian operator is generalized to the canonical central systems on the block Heisenberg groups. These systems of differential operators generalize the Heisenberg Laplacian and, like it, admit large algebras of conformal symmetries. The main result

A Bilinear Bogolyubov Argument in Abelian Groups
A bilinear Bogolyubov argument in abelian groups, Discrete Analysis 2024:20, 41 pp. Bogolyubov's argument states that if $A$ is a dense subset of $\mathbb Z_n$, then $2A-2A=\{x+y-z-w:x,y,z,w\in A\}$ contains a large and highly structured subset known ...
