摘要
This paper is concerned with the following Kirchhoff-Schriidinger-Poisson system {-(a+b integral(R3 )vertical bar del u vertical bar(2)dx)Delta u + V(x)u + mu phi u =lambda f(x)vertical bar u vertical bar(p-2)u + g(x)vertical bar u vertical bar(q-2)u, in R-3, -Delta phi = mu vertical bar u vertical bar(2), in R-3,R- where a > 0, b, mu >= 0, p is an element of [1,2), lambda E [4,6) and A > 0 is a parameter. Under some suitable assumptions on V(x), f(x) and g(x), we prove that the above system has at least two different nontrivial solutions via the Ekeland's variational principle and the Mountain Pass Theorem in critical point theory. Some recent results from the literature are improved and extended.
