Abstract
In this work we consider the following fractional Kirchhoff equations with singular nonlinearity:
where Omega is a bounded domain in R-n with smooth boundary is the fractional Sobolev exponent,., mu are two parameters, a, are non-negative weight functions, M is a continuous function, given by and is the fractional Laplacien 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.
