Optimal Control Problems of a Class of Nonlinear Degenerate Parabolic Equations

open access: yesMathematics
The optimal control problems of degenerate parabolic equations have many applications in economics, physics, climatology, and so on. Motivated by the applications, we consider the optimal control problems of a class of nonlinear degenerate parabolic ...

On Two Coupled Degenerate Parabolic Equations Motivated by Thermodynamics [PDF]

open access: yesJournal of nonlinear science, 2021
We discuss a system of two coupled parabolic equations that have degenerate diffusion constants depending on the energy-like variable. The dissipation of the velocity-like variable is fed as a source term into the energy equation leading to conservation ...

Null controllability of strongly degenerate parabolic equations                                                          

open access: yesE S A I M: Control, Optimisation and Calculus of Variations, 2023
We consider linear one-dimensional strongly degenerate parabolic equations with measurable coefficients that may be degenerate or singular. Taking 0 as the point where the strong degeneracy occurs, we assume that the coefficient a = a(x) in the principal

The Cauchy Problem for Parabolic Equations with Degeneration [PDF]

open access: yesAdvances in Mathematical Physics, 2020
Annotation. For a second-order parabolic equation, the multipoint in time Cauchy problem is considered. The coefficients of the equation and the boundary condition have power singularities of arbitrary order in time and space variables on a certain set of points.
