Harnack type inequality for non-negative solutions of second-order degenerate parabolic equations in divergent form

Electronic Journal of Differential Equations, 2016
We study a class of second-order degenerate parabolic equations in divergent form. We prove two analogues of the Harnack inequality, one for non-negative weak solutions, an another for non-negative solutions.

UNIFORM BMO ESTIMATE OF PARABOLIC EQUATIONS AND GLOBAL WELL-POSEDNESS OF THE THERMISTOR PROBLEM

Forum of Mathematics, Sigma, 2015
We prove global well-posedness of the time-dependent degenerate thermistor problem by establishing a uniform-in-time bounded mean ocsillation (BMO) estimate of inhomogeneous parabolic equations.

A multiplicity result for a class of quasilinear elliptic and parabolic problems

Electronic Journal of Differential Equations, 1997
We prove the existence of infinitely many solutions for a class of quasilinear elliptic and parabolic equations, subject respectively to Dirichlet and Dirichlet-periodic boundary conditions.

Null controllability of semilinear degenerate parabolic equations in bounded domains

Electronic Journal of Differential Equations, 2006
In this paper we study controllability properties for semilinear degenerate parabolic equations with nonlinearities involving the first derivative in a bounded domain of R. Due to degeneracy, classical null controllability results do not hold in general.

Convergence analysis of option drift rate inverse problem based on degenerate parabolic equation

Results in Applied Mathematics
In this paper, we study the convergence of the inverse drift rate problem of option pricing based on degenerate parabolic equations, aiming to recover the stock price drift rate function by known option market prices.
