讲座内容: I shall discuss some striking new results in the analysis of double phase problems. In the isotropic case, starting from the classical eigenvalue problem for the Laplace operator, we can observe the presence of a continuous spectrum provided that the source term is affected by another operator. In the anisotropic case, I shall establish sufficient conditions for the existence of solutions for the Lane-Emden equation in a mixed subcritical-critical-supercritical regime.
