Quantitative stability for quasilinear parabolic equations
Tapio Kurkinen, Qing Liu
We examine the stability of a class of quasilinear parabolic partial differential equations under perturbations. We are interested in the behavior of viscosity solutions as the per…

Liouville-type theorems for fully nonlinear elliptic and parabolic equations with boundary degeneracy
Qing Liu, Erbol Zhanpeisov
We study a class of fully nonlinear boundary-degenerate elliptic equations, for which we prove that u \equiv 0 is the only solution. Although no boundary conditions are posed toget…
