Self-similar solutions in a sector for a quasilinear parabolic equation

open access: yesNetworks and Heterogeneous Media, 2012
We study a two-point free boundary problem in a sector for aquasilinear parabolic equation. The boundaryconditions are assumed to be spatially and temporally 'self-similar' in a special way.

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 ...

Finite-difference method for the Gamma equation on non-uniform grids

open access: yesVietnam Journal of Science, Technology and Engineering, 2022
We propose a new monotone finite-difference scheme for the second-order local approximation on a nonuniform grid that approximates the Dirichlet initial boundary value problem (IBVP) for the quasi-linear convection-diffusion equation with unbounded ...

Regularity for a class of quasilinear degenerate parabolic equations in the Heisenberg group

open access: yesMathematics in Engineering, 2021
We extend to the parabolic setting some of the ideas originated with Xiao Zhong's proof in [31] of the Hölder regularity of $p-$harmonic functions in the Heisenberg group $\mathbb{H}^n$. Given a number $p\ge 2$, in this paper we establish the $C^{\infty}$

Existence and smoothing effects of the initial-boundary value problem for \partial u/\partial t-\Delta\sigma(u)=0 in time-dependent domains [PDF]

open access: yesOpuscula Mathematica, 2023
We show the existence, smoothing effects and decay properties of solutions to the initial-boundary value problem for a generalized porous medium type parabolic equations of the form \[u_t-\Delta \sigma(u) =0 \quad \text{in } Q(0, T)\] with the initial ...
