Sunto
In questo lavoro si provano risultati di regolarità per minimi di funzionali scalari $\int f (x, u, Du)$ a crescita non-standard di tipo $p(x)$, cioè: $$L^{-1} |z|^{p(x)} \leq f (x, s , z)\leq L(1+|z|^{p(x)}).$$ Si considerano per la funzione esponente $p(x)>1$ ipotesi di regolarità ottimali.
