Gao We · Journal of Kunming University · 2014
Determine the isolated toughness bound for fractional( g,f,n')-critical deleted graph in terms of the necessary and sufficient conditions of fractional( g,f,n')-critical deleted graph and the technology of minimal counterexample construction. It is presented that a graph is fractional( g,f,n')-critical deleted if δ( G) ≥bn'/a+( b +1)24a+ b and I( G) {b2+ bn'-1/a,if b a,b + n', if a =b.
