Coloring of graph of ring with respect to idempotents [PDF]
Mathematica BohemicaLet $R$ be a ring with nonzero identity. A graph $G_{{\rm Id}}(R)$ of $R$ with respect to idempotents of $R$ has elements of $R$ as vertices and distinct vertices $x$, $y$ are adjacent if and only if $x + y$ is an idempotent of $R$.

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 ...

Approximate truth of perfectness: An experimental test [PDF]
, 2012 Approximate truth refers to the principle that border cases should be analyzed by solving generic cases and solving border cases as limits of generic ones (Brennan et al., 2008). Our study experimentally explores whether this conceptual principle is also

Best System of Creation according to Transcendent Philosophy [PDF]
حکمت صدرایی, 2019 Best system of creation means the best and most perfect system that God created. The question is that whether this actual creation system is the most perfect possible world or not.

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

How perfect are perfect vortex beams? [PDF]
Optics Letters, 2019 Perfect (optical) vortex (PV) beams are fields which are mooted to be independent of the orbital angular momentum (OAM) they carry. To date, the best experimental approximation of these modes is obtained from passing Bessel-Gaussian beams through a Fourier lens.

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 ...

Advances in Applied Mathematics, 2016 We introduce a variant of de Bruijn words that we call perfect necklaces. Fix a finite alphabet. Recall that a word is a finite sequence of symbols in the alphabet and a circular word, or necklace, is the equivalence class of a word under rotations. For positive integers k and n, we call a necklace (k,n)-perfect if each word of length k occurs exactly ...
