A note on the zero divisor graph of a lattice [PDF]

Transactions on Combinatorics, 2014
Let $L$ be a lattice with the least element $0$. An element $xin L$ is a zero divisor if $xwedge y=0$ for some $yin L^*=Lsetminus left{0right}$. The set of all zero divisors is denoted by $Z(L)$.

Some results concerning exponential divisors

International Journal of Mathematics and Mathematical Sciences, 1988
If the natural number n has the canonical form p1a1p2a2…prar then d=p1b1p2b2…prbr is said to be an exponential divisor of n if bi|ai for i=1,2,…,r. The sum of the exponential divisors of n is denoted by σ(e)(n). n is said to be an e-perfect number if σ(e)

SMARANDACHE ANTI ZERO DIVISORS

Science Journal of University of Zakho
In this paper, we study and discuss the concept of Smarandache anti zero divisor (SAZD) element of the ring  and the group ring , where  is a cyclic group of order  generated by . Moreover, we introduce and discuss the concept of SAZD ideal of the ring .

Note on Quasi-Numerically Positive Log Canonical Divisors

Journal of Mathematics, 2015
We propose a subconjecture that implies the semiampleness conjecture for quasi-numerically positive log canonical divisors and prove the ampleness in some elementary cases.

The divisor function and divisor problem

, 2013
The purpose of this text is twofold. First we discuss some divisor problems involving Paul Erd\H os (1913-1996), whose centenary of birth is this year. In the second part some recent results on divisor problems are discussed, and their connection with the powers moments of $| (\frac{1}{2}+it)|$ is pointed out.

τ-IRREDUCIBLE DIVISOR GRAPHS IN COMMUTATIVE RINGS WITH ZERO-DIVISORS

International Electronic Journal of Algebra, 2015
In this paper, we continue the program initiated by I. Beck's now classical paper concerning zero-divisor graphs of commutative rings. After the success of much research regarding zero-divisor graphs, many authors have turned their attention to studying divisor graphs of non-zero elements in integral domains.

Mumford divisors

, 2018
We define the notion of Mumford divisors, argue that they are the natural divisors to study on reduced but non-normal varieties and prove a structure theorem for the Mumford class group.

A C 2,α,β estimate for complex Monge–Ampère type equations with conic sigularities

Advanced Nonlinear Studies
In this paper, we give an alternative approach to the C 2,α,β estimate for complex Monge-Ampère equations with cone singularities along simple normal crossing divisors.

Real divisors on real curves

Le Matematiche, 1999
Let C be an affine or projective smooth real algebraic curve, having a non-empty real part. Then every divisor E on C, which is linearly equivalent to its conjugate E^c , is also equivalent to a divisor supported on a set of real points of C.
