Regularity and geometric character of solution of a degenerate parabolic equation

open access: yesBulletin of Mathematical Sciences, 2016
This work studies the regularity and the geometric significance of solution of the Cauchy problem for a degenerate parabolic equation $$u_{t}=\Delta {}u^{m}$$ u t = Δ u m . Our main objective is to improve the H $$\ddot{o}$$ o ¨ lder estimate obtained by

Null controllability of degenerate parabolic equation with memory [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2020
In this paper, we analyze the null controllability property for a degenerate parabolic equation involving memory terms with a locally distributed control. We first derive a null controllability result for a nonhomogeneous degenerate heat equation via new

Discontinuous “viscosity” solutions of a degenerate parabolic equation [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1990
We study a nonlinear degenerate parabolic equation of the second order. Regularizing the equation by adding some artificial viscosity, we construct a generalized solution. We show that this solution is not necessarily continuous at all points.

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

open access: goldResults 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.

On a degenerate parabolic equation from double phase convection [PDF]

open access: goldAdvances in Difference Equations, 2021
The initial-boundary value problem of a degenerate parabolic equation arising from double phase convection is considered. Let a ( x ) $a(x)$ and b ( x ) $b(x)$ be the diffusion coefficients corresponding to the double phase respectively.

Fractional Sobolev regularity for solutions to a strongly degenerate parabolic equation [PDF]

open access: yesForum mathematicum, 2022
We carry on the investigation started in [P. Ambrosio and A. Passarelli di Napoli, Regularity results for a class of widely degenerate parabolic equations, preprint 2022, version 3, https://arxiv.org/abs/2204.05966v3] about the regularity of weak ...

A Fredholm Transformation for the Rapid Stabilization of a Degenerate Parabolic Equation [PDF]

open access: yesSIAM Journal of Control and Optimization, 2020
This paper deals with the rapid stabilization of a degenerate parabolic equation with a right Dirich-let control. Our strategy consists in applying a backstepping strategy, which seeks to find an invertible transformation mapping the degenerate parabolic

Higher regularity for weak solutions to degenerate parabolic problems [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2023
In this paper, we study two related features of the regularity of the weak solutions to the following strongly degenerate parabolic equation $$\begin{aligned} u_t-\textrm{div}\left( \left( \left| Du\right| -1\right) _+^{p-1}\frac{Du}{\left| Du\right ...
