Abstract

The aim of this paper is to study the existence of solutions for Kirchhoff type equations involving the nonlocal fractional Laplacian with critical Sobolev-Hardy exponent where are nonnegative constants and is called the critical Sobolev-Hardy exponent, . Here with is the fractional r-Laplace operator. Ω is an open bounded subset of with smooth boundary and . are continuous functions and f is a Carathéodory function which does not satisfy the Ambrosetti-Rabinowitz condition. By using the Mountain Pass Theorem, we obtain the existence of solutions for the above problem. Furthermore, using Fountain Theorem, we get the existence of infinitely many solutions for the above problem when . We also study the existence of two nontrivial solutions for the Kirchhoff type equation involving the fractional p-Laplacian via Morse theory. Finally, we consider the case and study a degenerate Kirchhoff equation involving Trudinger-Moser nonlinearity. In our best knowledge, it is the first time our problems are studied in this area.
