Time-interior gradient estimates for quasilinear parabolic equations [PDF]

open access: yesIndiana University Mathematics Journal 58 (2009) 351--380, 2013
Bounded smooth solutions of the Dirichlet and Neumann problems for a wide variety of quasilinear parabolic equations, including graphical anisotropic mean curvature flows, have gradient bounded in terms of oscillation and elapsed time.

Quasilinear parabolic stochastic partial differential equations: existence, uniqueness [PDF]

open access: yesarXiv, 2015
In this paper, we provide a direct approach to the existence and uniqueness of strong (in the probabilistic sense) and weak (in the PDE sense) solutions to quasilinear stochastic partial differential equations, which are neither monotone nor locally monotone.

On a gradient maximum principle for some quasilinear parabolic equations on convex domains [PDF]

open access: yesarXiv, 2016
We establish a spatial gradient maximum principle for classical solutions to the initial and Neumann boundary value problem of some quasilinear parabolic equations on smooth convex domains.

Nonexistence of stable solutions to quasilinear elliptic equations on Riemannian manifolds [PDF]

open access: yesarXiv, 2016
We prove nonexistence of nontrivial, possibly sign changing, stable solutions to a class of quasilinear elliptic equations with a potential on Riemannian manifolds, under suitable weighted volume growth conditions on geodesic balls.

Local behavior of solutions of quasilinear parabolic equations on metric spaces [PDF]

open access: yesarXiv, 2017
We introduce a notion of quasilinear parabolic equations over metric measure spaces. Under sharp structural conditions, we prove that local weak solutions are locally bounded and satisfy the parabolic Harnack inequality. Applications include the parabolic maximum principle and pointwise estimates for weak solutions.

Infinitely many solutions for quasilinear Schrödinger equation with concave-convex nonlinearities

open access: yesBoundary Value Problems
In this work, we study the existence of infinitely many solutions to the following quasilinear Schrödinger equations with a parameter α and a concave-convex nonlinearity: 0.1 − Δ p u + V ( x ) | u | p − 2 u − Δ p ( | u | 2 α ) | u | 2 α − 2 u = λ h 1 ( x

We give a proof for the asymptotic exponential stability of equilibria of quasilinear parabolic evolution equations in admissible interpolation spaces.
