报告摘要:
We study semiclassical states of the nonlinear Dirac equation. Our main result deals with standing wave solutions that concentrate near a critical point of the potential. Standard methods applicable to nonlinear Schrodinger equations, like Lyapunov-Schmidt reduction or penalization, do not work, not even for the homogeneous nonlinearity. We develop a variational method for the strongly indefinite functional associated to the problem.
