Prof. Dr. Gianni Dal Maso (SISSA, Trieste): New results on homogenisation of free discontinuity problems. Kolloquium Partial Differential Equations
Tuesday, 06.06.2023 15:30 im Raum SRZ 203
We study deterministic and stochastic homogenisation problems for free discontinuity functionals under new hypotheses on the surface energies. The results are based on a compactness theorem with respect to Gamma-convergence, on the characterisation of the integrands of the Gamma-limit by means of limits of minimum values of some auxiliary minimum problems on small cubes, and on the subadditive ergodic theorem for the stochastic part.
