D3 Brane Action and Fermion Zero Modes in Presence of Background Flux [PDF]

open access: yes, 2005
We derive the fermion bilinear terms in the world volume action for a D3 brane in the presence of background flux. In six-dimensional compactifications non-perturbative corrections to the superpotential can arise from an Euclidean D3-brane instanton ...

NO ZERO DIVISOR FOR WICK PRODUCT IN (S)* [PDF]

open access: yesInfinite Dimensional Analysis, Quantum Probability and Related Topics, 2008
In White Noise Analysis (WNA), various random quantities are analyzed as elements of (S)*, the space of Hida distributions.1 Hida distributions are generalized functions of white noise, which is to be naturally viewed as the derivative of the Brownian motion. On (S)*, the Wick product is defined in terms of the [Formula: see text]-transform.

Removable singularities of the CscK metric [PDF]

open access: yes, 2015
In this paper, we consider a CscK metric defined away from divisor and with metric upper bound and lower bound going to zero in certain rate. And we'll prove that this "nicely" behaved metric is a smooth CscK metric across the divisor.Comment ...

Zero divisors and units with small supports in group algebras of torsion-free groups

open access: yes, 2017
We associate a graph to a possible non-zero zero-divisor in the group algebra of a torsion-free group.Comment: to appear in Communications in Algebra.

Probabilistic characterizations of some finite ring of matrices and its zero divisor graph [PDF]

open access: yes, 2020
Let R be a finite ring. In this study, the probability that two random elements chosen from a finite ring have product zero is determined for some finite ring of matrices over Zn.

Zero-divisor graphs of idealizations

open access: yesJournal of Pure and Applied Algebra, 2006
AbstractWe consider zero-divisor graphs of idealizations of commutative rings. Specifically, we look at the preservation, or lack thereof, of the diameter and girth of the zero-divisor graph of a ring when extending to idealizations of the ring.

Planar zero-divisor graphs

open access: yesJournal of Algebra, 2007
AbstractThis paper answers the question of Anderson, Frazier, Lauve, and Livingston: for which finite commutative rings R is the zero-divisor graph Γ(R) planar? We build upon and extend work of Akbari, Maimani, and Yassemi, who proved that if R is any local ring with more than 32 elements, and R is not a field, then Γ(R) is not planar.

Reduced zero-divisor graphs of posets [PDF]

open access: yesTransactions on Combinatorics, 2018
This paper investigates properties of the reduced zero-divisor graph of a poset. We show that a vertex is an annihilator prime ideal if and only if it is adjacent to all other annihilator prime ideals and there are always two annihilator prime ideals ...

On the existence of dimension zero divisors in algebraic function fields defined over F_q

open access: yes, 2009
Let F/F_q be an algebraic function field of genus g defined over a finite field F_q. We obtain new results on the existence, the number and the density of dimension zero divisors of degree g-k in F where k is a positive integer.

Distances in zero-divisor and total graphs from commutative rings–A survey

open access: yesAKCE International Journal of Graphs and Combinatorics, 2016
There are so many ways to construct graphs from algebraic structures. Most popular constructions are Cayley graphs, commuting graphs and non-commuting graphs from finite groups and zero-divisor graphs and total graphs from commutative rings.
