摘要
In this work we study the fractional p-Laplacian equation with singular nonlinearity {(-Delta)(p)(s) u = lambda a(x)vertical bar u vertical bar(q-2)u + 1-alpha/2-alpha-beta c(x)vertical bar u vertical bar(-alpha)vertical bar v vertical bar(1-beta), in Omega, (-Delta)(p)(s)v = mu b(x)vertical bar v vertical bar(q-2)v + 1-beta/2-alpha-beta c(x)vertical bar u vertical bar(1-alpha)vertical bar v vertical bar(-beta), in Omega, u = v = 0, in R-N\Omega, where 0 < alpha < 1, 0 < beta < 1, 2-alpha-beta < p < q < p(s)*, p(s)* = N/N-ps is the fractional Sobolev exponent, lambda, mu are two parameters, a, b, c is an element of C(<(Omega)over bar>) are non-negative weight functions with compact support in Omega, and (-Delta)(p)(s) is the fractional p-Laplace operator. We use the Nehari manifold approach and some variational techniques in order to show the existence and multiplicity of positive solutions of the above problem with respect to the parameter lambda and mu.
