Inhomogeneous extreme forms [PDF]
, 2010 G.F. Voronoi (1868-1908) wrote two memoirs in which he describes two reduction theories for lattices, well-suited for sphere packing and covering problems.

Perfect Matchings and Perfect Powers [PDF]
Journal of Algebraic Combinatorics, 2003 In the last decade there have been many results about special families of graphs whose number of perfect matchings is given by perfect or near perfect powers. In this paper we present an approach that allows proving them in a unified way. We use this approach to prove a conjecture of James Propp stating that the number of tilings of the so-called Aztec

Environmental Justice in Quran and Hadith Teachings [PDF]
تحقیقات علوم قرآن و حدیث, 2011 The incorrect interaction of human beings with the environment has lead to such an environmental unbalance that besides destroying the nature, it has disregarded justice in using nature resources.

On the perfectness of C^{∞,s}-diffeomorphism groups on a foliated manifold [PDF]
Opuscula Mathematica, 2008 The notion of \(C^{r,s}\) and \(C^{\infty,s}\)-diffeomorphisms is introduced. It is shown that the identity component of the group of leaf preserving \(C^{\infty,s}\)-diffeomorphisms with compact supports is perfect.

The cubic power graph of finite abelian groups
AKCE International Journal of Graphs and Combinatorics, 2021 Let G be a finite abelian group with identity 0. For an integer the additive power graph of G is the simple undirected graph with vertex set G in which two distinct vertices x and y are adjacent if and only if x + y = nt for some with When the additive ...

Perfectness of the essential graph for modules over commutative rings [PDF]
AUT Journal of Mathematics and ComputingLet $R$ be a commutative ring and $M$ be an $R$-module. The essential graph of $M$, denoted by $EG(M)$ is a simple graph with vertex set $Z(M) \setminus\operatorname{Ann}(M)$ and two distinct vertices $x,y \in Z(M) \setminus \operatorname{Ann}(M)$ are ...

Improved Lattice Actions with Chemical Potential [PDF]
, 1998 We give a prescription how to include a chemical potential \mu into a general lattice action. This inclusion does not cause any lattice artifacts. Hence its application to an improved - or even perfect - action at \mu =0 yields an improved resp.
