This paper deals with the local solvability of initial value problem for Kaup-Kupershmidt equations.Indeed,using Bourgain method,we prove that the Cauchy proble
Let G be a group.We consider the set cd(G){m},where m ∈ cd(G).We define the graph ρ(G-m) whose vertex set is ρ(G-m),the set of primes dividing degrees in cd(
