Classification of heteroclinic orbits of semilinear parabolic equations with a polynomial nonlinearity

open access: yesElectronic Journal of Differential Equations, 2011
For a given semilinear parabolic equation with polynomial nonlinearity, many solutions blow up in finite time. For a certain class of these equations, we show that some of the solutions which do not blow up actually tend to equilibria.

Global well-posedness of semilinear hyperbolic equations, parabolic equations and Schrodinger equations

open access: yesElectronic Journal of Differential Equations, 2018
This article studies the existence and nonexistence of global solutions to the initial boundary value problems for semilinear wave and heat equation, and for Cauchy problem of nonlinear Schrodinger equation.

A mixed semilinear parabolic problem from combustion theory

open access: yesElectronic Journal of Differential Equations, 2001
We prove existence, uniqueness, and regularity of the solution to a mixed initial boundary-value problem. The equation is semilinear uniformly parabolic with principal part in divergence form, in a non-cylindrical space-time domain.

Blow-up for a semilinear heat equation with moving nonlinear reaction

open access: yesElectronic Journal of Differential Equations, 2018
We study the behavior of solutions of the semilinear problem $$\displaylines{ u_t=u_{xx}+(1+(T-t)^{-\alpha}\chi_{\{|x|0$ and p>0 We describe, in terms of the parameters when the solution is bounded and when it blows up.

Recent results and open problems on parabolic equations with gradient nonlinearities

open access: yesElectronic Journal of Differential Equations, 2001
We survey recent results and present a number of open problems concerning the large-time behavior of solutions of semilinear parabolic equations with gradient nonlinearities. We focus on the model equation with a dissipative gradient term $$u_t-Delta u=u^
