Query: A nonlinear general Neumann problem involving two critical   We discuss the existence of solutions of nonlinear problem involving,two
critical Sobolev exponents. we will ll out the su cient conditions to nd
solutions for the problem in presence of a nonlinear Neumann boundary data with
a critical nonlinearity. \
