A sufficient condition for graphs to be(g,f,k)-critical graphs
We obtain a sufficient condition which the general transportation problems have optimal signature.
In this paper, Green's formula is extended to nonsmooth functions. A necessary and sufficient condition about Green's formula is gained.
Material implication, which describes a kind of truth value function, is naturally not the logic abstract of the sufficient condition relation.
So it's a sufficient condition for an argument being valid that there is no possible situation where the premises are true and the conclusion false. And that's a necessary condition too.
Results A necessary and sufficient condition for the temopral stability of steady state is provided and the necessary conditon for the bifurcation of this steady state to spatially non-uniform solution is also given.
