A permutations representation that knows what " Eulerian" means
Discrete Mathematics & Theoretical Computer Science, 2001 Eulerian numbers (and ``Alternate Eulerian numbers'') are often interpreted as distributions of statistics defined over the Symmetric group. The main purpose of this paper is to define a way to represent permutations that provides some other ...

SYMMETRY OF EXTENDING PROPERTIES IN NONSINGULAR UTUMI RINGS [PDF]
Surveys in Mathematics and its Applications, 2020 his paper presents the right-left symmetry of the CS and max-min CS conditions on nonsingular rings, and generalization to nonsingular modules. We prove that a ring is right nonsingular right CS and left Utumi if and only if it is left nonsingular left ...

Overlap-free symmetric D 0 Lwords
Discrete Mathematics & Theoretical Computer Science, 2001 A D0L word on an alphabet Σ={0,1,…,q-1} is called symmetric if it is a fixed point w=φ(w) of a morphism φ:Σ * → Σ * defined by φ(i)= t 1 + i t 2 + i … t m + i for some word t 1 t 2 … t m (equal to φ(0)) and every i ∈ Σ; here a means

Inequalities for Single Crystal Tube Growth by Edge-Defined Film-Fed Growth Technique
Journal of Inequalities and Applications, 2009 The axi-symmetric Young-Laplace differential equation is analyzed. Solutions of this equation can describe the outer or inner free surface of a static meniscus (the static liquid bridge free surface between the shaper and the crystal surface) occurring ...

Energy of binary labeled graphs [PDF]
Transactions on Combinatorics, 2013 Let G be graph with vertex set V(G) and edge set E(G) and the set A={0,1}. A mapping is called binary vertex labeling of G and l(v) is called the label of the vertex v under l.

The b-chromatic number of power graphs
Discrete Mathematics & Theoretical Computer Science, 2003 The b-chromatic number of a graph G is defined as the maximum number k of colors that can be used to color the vertices of G, such that we obtain a proper coloring and each color i, with 1 ≤ i≤ k, has at least one representant x i adjacent to a
