Abstract: Consider the following general nonlinear system
$Au = N(u); u \in H$
where H is a Hilbert space, A a self-adjoint operator, and N a gradient
map. The talk will focus on:

  •  the general variational setting
  •  Dirac systems on spin manifolds
  •  Dirac systems on flat space
  •  Reaction-diffusion systems, etc.

We are interested in the existence (multiplicity, concentration) of solutions.
