Let [Formula: see text] denote the incidence algebra of a locally finite poset [Formula: see text] over a field [Formula: see text] and [Formula: see text] some equivalence relation on the set of generators of [Formula: see text]. Then [Formula: see

For a graph $G$ and an abelian group $A$, a labeling of the vertices of $G$ induces a labeling of the edges via the sum of adjacent vertex labels. Hovey introduced the notion of an $A$-cordial vertex labeling when both the vertex and edge labels are

We compute the Hilbert series of the graded algebra of real regular functions on the symplectic quotient associated to an [Formula: see text]-module and give an explicit expression for the first nonzero coefficient of the Laurent expansion of the Hil

Let $n\ge 1$ and $A$ be a commutative algebra of the form $\boldsymbol k[x_1,x_2,\dots, x_n]/I$ where $\boldsymbol k$ is a field of characteristic $0$ and $I\subseteq \boldsymbol k[x_1,x_2,\dots, x_n]$ is an ideal. Assume that there is a Poisson brac

We compute the Hilbert series of the graded algebra of real regular functions on a linear symplectic quotient by the $2$-torus as well as the first four coefficients of the Laurent expansion of this Hilbert series at $t = 1$. We describe an algorithm

A group homomorphism e : H → G {e:H\to G} is a cellular cover of G if for every homomorphism φ : H → G {\varphi:H\to G} there is a unique homomorphism φ ¯ : H → H {\bar{\varphi}:H\to H} such that φ ¯ e = φ {\bar{\varphi}e=\varphi} . G

We consider Ramsey-type problems associated to collections of sets in R n satisfying a standard geometric regularity condition. In particular, let { R j } j = 1 N be a collection of measurable sets in R n such that every R j is contained in a cube Q

A remarkable theorem of Besicovitch is that an integrable function f f on R 2 \mathbb {R}^2 is strongly differentiable if its associated strong maximal function M S f M_S f is finite a.e. We provide an analogue of Besicovitch’s result in the contex

We prove in ZFC that an abelian group $C$ is cotorsion if and only if $\operatorname{Ext}(F,C) = 0$ for every $\aleph_k$-free group $F$, and discuss some consequences and related results. This short note includes a condensed overview of the $\bar\lam
