Abstract

In this paper we consider integral functionals of the form

with convex integrand satisfying growth conditions. We prove local higher differentiability results for bounded minimizers of the functional under dimension-free conditions on the gap between the growth and the coercivity exponents.

As a novel feature, the main results are achieved through uniform higher differentiability estimates for solutions to a class of auxiliary problems, constructed adding singular higher order perturbations to the integrand.
