Regularity for fully nonlinear degenerate parabolic equations with strong absorption

João Vitor da Silva, João Vitor da Silva, Feida Jiang +1

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…

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…
