Uniform Lipschitz regularity for two-phase singularly perturbed fully nonlinear elliptic equations

Thialita M. Nascimento, Aelson Sobral, Eduardo V. Teixeira

We study sign-changing viscosity solutions of the singularly perturbed fully nonlinear equation $$ F(D^2u_\varepsilon) = \fracα{\varepsilon} β\left(\frac{u_\varepsilon}{\varepsilon…

Borderline regularity in singular free boundary problems

Damião J. Araújo, Aelson Sobral, Eduardo V. Teixeira +1

In this paper, we investigate the borderline regularity of local minimizers of energy functionals under minimal assumptions on the potential term $σ$ . When $σ$ is merely bounded an…

A limiting free boundary problem ruled by Aronsson's equation

J. D. Rossi, E. V. Teixeira

We study the behavior of $p$ -Dirichlet optimal design problem with volume constraint for $p$ large. As the limit as $p$ goes to infinity, we find a limiting free boundary problem g…
