摘要
Local minimizers of integral functionals of the calculus of variations are analyzed under growth conditions dictated by different lower and upper bounds for the integrand. Growths of non -necessarily power type are allowed. The local boundedness of the relevant minimizers is established under a suitable balance between the lower and the upper bounds. Classical minimizers, as well as quasi -minimizers are included in our discussion. Functionals subject to so-called p, q -growth conditions are embraced as special cases and the corresponding sharp results available in the literature are recovered. (c) 2024 The Author(s).
