摘要
In the present paper, by applying variant mountain pass theorem and Ekeland variational principle we study the existence of multiple nontrivial solutions for a class of Kirchhoff type problems with concave nonlinearity {-(a + b integral(Omega)vertical bar del vertical bar(2))Delta u - alpha(x)vertical bar u vertical bar(q-2)u + c(x, u), in Omega u = 0, on partial derivative Omega A new existence theorem and an interesting corollary of four nontrivial solutions are obtained.
