چکیده انگلیسی
We look for solutions E:ΩâR3 of the problem{âÃ(âÃE)+λE=|E|pâ2Ein ΩνÃE=0on âΩ on a bounded Lipschitz domain ΩâR3, where âà denotes the curl operator in R3. The equation describes the propagation of the time-harmonic electric field â{E(x)eiÏt} in a nonlinear isotropic material Ω with λ=âμεÏ2â¤0, where μ and ε stand for the permeability and the linear part of the permittivity of the material. The nonlinear term |E|pâ2E with p>2 is responsible for the nonlinear polarisation of Ω and the boundary conditions are those for Ω surrounded by a perfect conductor. The problem has a variational structure and we deal with the critical value p, for instance, in convex domains Ω or in domains with C1,1 boundary, p=6=2â is the Sobolev critical exponent and we get the quintic nonlinearity in the equation. We show that there exist a cylindrically symmetric ground state solution and a finite number of cylindrically symmetric bound states depending on λâ¤0. We develop a new critical point theory which allows to solve the problem, and which enables us to treat more general anisotropic media as well as other variational problems.
