## Abstract Jacobson, Levin, and Scheinerman introduced the fractional Ramsey function __r__~__f__~ (__a__~1~, __a__~2~, โฆ, __a__~__k__~) as an extension of the classical definition for Ramsey numbers. They determined an exact formula for the fractional Ramsey function for the case __k__=2. In this

โฆ Synopsis
In [ I ]I, Gandhi has stated the following conjecture on Genocchi numbl:rs:
. z;(t~-I)~ .
The meaning of the odd notation on the 1e:ft of (1) is as follows: write
. . . C(k+n-1)2 ; then
K(n+l,k)=k2K(n,k+lj-(k-l)2~(~~,k~ K(1,k)=k2-(k-1;j2 =2k--1
alId, af course, (1) is restated as
(1') C-1 1" 62, = K(n-R,l) 0 S ated in this way, this result is effectively the sari::: as that of [6] .

The aim of this paper is to show that for any n ยฅ N, n > 3, there exist a, b ยฅ N\* such that n=a+b, the ''lengths'' of a and b having the same parity (see the text for the definition of the ''length'' of a natural number). Also we will show that for any n ยฅ N, n > 2, n ] 5, 10, there exist a, b ยฅ N\

## Abstract Let __ir__(__G__) and ฮณ(__G__) be the irredundance number and the domination number of a graph __G__, respectively. A graph __G__ is called __irredundance perfect__ if __ir__(__H__)=ฮณ(__H__), for every induced subgraph __H__ of __G__. In this article we present a result which immediatel
