Totally disconnected locally compact groups locally of finite rank

, 2015
We study totally disconnected locally compact second countable (t.d.l.c.s.c.) groups that contain a compact open subgroup with finite rank. We show such groups that additionally admit a pro-$\pi$ compact open subgroup for some finite set of primes $\pi ...

Skolem-Noether for nilpotent products

, 2015
We consider the structure of groups and algebras that can be represented as automorphisms or derivations of distributive products -- which includes nonassociative rings, modules, forms, and commutation of groups and nonassociative loops.

The structure of the space of polynomial solutions to the canonical central systems of differential equations on the block Heisenberg groups: A generalization of a theorem of Korányi

Tohoku Mathematical Journal, 2018
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

The asymptotic shape theorem for generalized first passage percolation

, 2010
We generalize the asymptotic shape theorem in first passage percolation on $\mathbb{Z}^d$ to cover the case of general semimetrics. We prove a structure theorem for equivariant semimetrics on topological groups and an extended version of the maximal ...

A generalized Cartan decomposition for the double coset space U(n_1) x U(n_2) x U(n_3)) U(n) / U(p) x U(q)

, 2006
Motivated by recent developments on visible actions on complex manifolds, we raise a question whether or not the multiplication of three subgroups $L$, $G'$ and $H$ surjects a Lie group $G$ in the setting that $G/H$ carries a complex structure and ...

A Bilinear Bogolyubov Argument in Abelian Groups

Discrete Analysis
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 ...

Properties of centered random walks on locally compact groups and Lie groups

, 2007
The basic aim of this paper is to study asymptotic properties of the convolution powers K^(n) = K * K * ... * K of a possibly non-symmetric probability density K on a locally compact, compactly generated group G. If K is centered, we show that the Markov

Vanishing theorems for ample vector bundles

, 1996
We prove a general vanishing theorem for the cohomology of products of symmetric and skew-symmetric powers of an ample vector bundle on a smooth complex projective variety.

Carrier and nerve theorems in the extension theory [PDF]

, 2005
We show that a regular cover of a general topological space provides structure similar to a triangulation. In this general setting we define analogues of simplicial maps and prove their existence and uniqueness up to homotopy.

Topological comparison theorems for Bredon motivic cohomology

, 2018
We prove equivariant versions of the Beilinson-Lichtenbaum conjecture for Bredon motivic cohomology of smooth complex and real varieties with an action of the group of order two.
