Quasilinear Parabolic Equations Associated with Semilinear Parabolic Equations

open access: yesMathematics, 2023
We formulate a quasilinear parabolic equation describing the behavior of the global-in-time solution to a semilinear parabolic equation. We study this equation in accordance with the blow-up and quenching patterns of the solution to the original ...

Global solutions to semilinear parabolic equations driven by mixed local–nonlocal operators [PDF]

open access: greenBulletin of the London Mathematical Society, Volume 57, Issue 1, Page 265-284, January 2025.
Abstract We are concerned with the Cauchy problem for the semilinear parabolic equation driven by the mixed local–nonlocal operator L=−Δ+(−Δ)s$\mathcal {L}= -\Delta +(-\Delta)^s$, with a power‐like source term. We show that the so‐called Fujita phenomenon holds, and the critical value is exactly the same as for the fractional Laplacian.

Well-posedness of the solution of the fractional semilinear pseudo-parabolic equation [PDF]

open access: goldBoundary Value Problems, 2020
This article concerns the Cauchy problem for the fractional semilinear pseudo-parabolic equation. Through the Green’s function method, we prove the pointwise convergence rate of the solution.

Fourth order semilinear parabolic equations [PDF]

open access: bronzeTsukuba Journal of Mathematics, 1992
The aim of this paper is to give a simple proof of the existence of a smooth solution to the semilinear parabolic equation with fourth order elliptic operator: \[ u_ t= -\varepsilon^ 2 \Delta^ 2 u+ f(t,x,u,u_ x,u_{xx}),\tag{1} \] \(x\in \Omega\subset \mathbb{R}^ n\), \(\Omega\) is a bounded domain, \(t\in [0,T_{\max})\), \(T_{\max}\leq +\infty\).

Lack of smoothing for bounded solutions of a semilinear parabolic equation

open access: yesAdvances in Nonlinear Analysis, 2020
We study a semilinear parabolic equation that possesses global bounded weak solutions whose gradient has a singularity in the interior of the domain for all t > 0.
