A Note on Relaxed Divisor Methods
The purpose of this note is to add some important properties to the results obtained in [2]. Specifically, it is shown that (i) an apportionment for relaxed divisor methods remains unchanged over an interval and (ii) any relaxed divisor method approaches the Webster method as the house size increases.
متن کاملRelaxed Divisor Methods and Their Seat Biases
A class of methods of apportionment called the relaxed divisor methods is introduced here. It is theoretically shown that their biases between small and large states decrease and eventually approach zero as the house size increases. Because the methods of Hill and Webster are examples of the class, they both are practically unbiased for the house size large enough. However, computer simulations...
متن کاملA note on relaxed and flexible GMRES
We consider the solution of a linear system of equations using the GMRES iterative method. In [3], a strategy to relax the accuracy of the matrix-vector product is proposed for general systems and illustrated on a large set of numerical experiments. This work is based on some heuristic considerations and proposes a strategy that often enables a convergence of the GMRES iterates xk within a rela...
متن کاملa note on the zero divisor graph of a lattice
abstract. 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 $z(l)$. we associate a simple graph $gamma(l)$ to $l$ with vertex set $z(l)^*=z(l)setminus left{0right}$, the set of non-zero zero divisors of $l$ and distinct $x,yin z(l)^*$ are adjacent if and only...
متن کاملA Note on Zero Divisor Graph Over Rings
In this article we discuss the graphs of the sets of zero-divisors of a ring. Now let R be a ring. Let G be a graph with elements of R as vertices such that two non-zero elements a, b ∈ R are adjacent if ab = ba = 0. We examine such a graph and try to find out when such a graph is planar and when is it complete etc. Mathematics Subject Classification: Primary 16-xx, 05-xx; Secondary 05C50
