摘要：
We show how to infer sharp partial regularity results for relaxed minimizers of degenerate, nonuniformly elliptic quasiconvex functionals, using tools from Nonlinear Potential Theory. In particular, in the setting of functionals with (p, q)growth - according to the terminology of Marcellini [52] - we derive optimal local regularity criteria under minimal assumptions on the data.
