Global regularity for degenerate fully nonlinear elliptic equations

Jiangwen Wang, Feida Jiang

In this paper, we prove global regularity for Dirichlet problem of a class of degenerate fully nonlinear elliptic equations on domain. This corresponds to the bou…

Regularity for fully nonlinear degenerate parabolic equations with strong absorption

João Vitor da Silva, Feida Jiang, Jiangwen Wang

In this paper, we investigate dead-core problems for fully nonlinear degenerate parabolic equations with strong absorption, \begin{equation*} |Du|^{p} F(D^{2}u) - u_{t} = λ_{0}(x,t…

Improved regularity estimates for degenerate or singular fully nonlinear dead-core systems and Hénon-type equations

Jiangwen Wang, Feida Jiang

In this paper, we study the degenerate or singular fully nonlinear dead-core systems coupled with strong absorption terms. We establish several properties, including improved regul…

Regularity of solutions for degenerate or singular fully nonlinear integro-differential equations

Jiangwen Wang, Feida Jiang

We study a series of regularity results for solutions to a degenerate or singular fully nonlinear integro-differential equation of the form $$- \big( σ_{1}(|Du|) + a(x) σ_{2}(|Du|)…
