چکیده
|
Bell's degree-variance varb for a graph g, with the degree sequence (d1,d2,…,dn) and size m, is defined as varb(g)=1n∑ni=1[di−2mn]2. in this paper, a new version of the irregularity measures of variance-type, denoted by varq, is introduced and discussed. based on a comparative study, it is demonstrated that the newly proposed irregularity measure varq possess a better discrimination ability than the classical bell's degree-variance in several cases.
