A quantitative Hopf-Oleinik lemma for degenerate fully nonlinear operators and applications to free boundary problems
Davide Giovagnoli, Enzo Maria Merlino, Diego Moreira
We prove a quantitative inhomogeneous Hopf-Oleinik lemma for viscosity solutions of and, more generally, for viscosity supersolutions of $|\nabla u|^α\…

Tangential contact of free boundaries and the fixed boundary for variational solutions to a free transmission Problem
Diego Moreira, Harish Shrivastava
In this article we study functionals of the following type here $A(x,u)= A_+(x)χ_{\{u>0\}}+A_-(x) χ_…

Tangential contact between free and fixed boundaries for variational solutions to variable coefficient Bernoulli type Free boundary problems
Diego Moreira, Harish Shrivastava
In this paper, we show that given appropriate boundary data, the free boundary and the fixed boundary of minimizers of functionals of type \eqref{functional} contact each other in…

Optimal Regularity in Transmission Problems]{Optimal regularity for variational solutions of free transmission problems
Diego Moreira, Harish Shrivastava
In this article we study functionals of the type considered in \cite{HS21}, i.e. here $A(x,u)= A_+(x)χ_{\{u>0\}}+A_…
