The Leray-Lions existence theorem under general growth conditions

Giovanni Cupini, Paolo Marcellini, Elvira Mascolo

We prove an existence result of weak solutions $u \in W_{0}^{1, p} (Ω) \cap W_{loc}^{1, q} (Ω)$ , to a Dirichlet problem for a second order elliptic equ…

Regularity for nonuniformly elliptic equations with $p, q -$ growth and explicit $x, u -$ dependence

Giovanni Cupini, Paolo Marcellini, Elvira Mascolo

We are interested in the regularity of weak solutions $u$ to the elliptic equation in divergence form; precisely in their local boundedness and their local Lipschitz continuity und…

On the harmonic characterization of the spheres: a sharp stability inequality and some of its consequences

Giovanni Cupini, Ermanno Lanconelli

Let $D$ be a bounded open subset of $R^{n}$ with $∣ \partial D ∣ < \infty$ and let $x_{0}$ be a point of $D$ . We introduce a new parameter, that we call Kuran gap of $\partial…
