Comparison results for the $p$ -torsional rigidity on convex domains

Cristian Enache, Mihai Mihailescu, Denisa Stancu-Dumitru

For each open, bounded and convex domain $I^c ◯ \subset R^{D},$ $D \geq 2$ , and each real number $p > 1,$ we denote by $u_{p}$ the $p$ \emph{-torsion function} on $I^c ◯$ , i.e. the s…

Minimum principles and a priori estimates for 2-Hessian problems

Cristian Enache

In this paper we investigate a class of $2$ -Hessian equations and establish a minimum principle for a $P$ -function in the sense of L.E. Payne (see R. Sperb \cite{Sp81}). The analys…

Some minimum principles for a class of nonlinear elliptic problems in divergence form

Cristian Enache, Rafael Lopez

In this paper we study a general class of nonlinear elliptic problems in divergence form. First, we prove that the solutions to these problems satisfy a convexity property when the…
