Uniform blow-up profiles and boundary behavior for diffusion equations with nonlocal nonlinear source

P Souplet - Journal of Differential Equations, 1999 - Elsevier
In this paper, we introduce a new method for investigating the rate and profile of blow-up of
solutions of diffusion equations with nonlocal nonlinear reaction terms. For large classes of …

Blow-up for parabolic and hyperbolic problems with variable exponents

JP Pinasco - Nonlinear Analysis: Theory, Methods & Applications, 2009 - Elsevier
In this paper, we study the blow up problem for positive solutions of parabolic and hyperbolic
problems with reaction terms of local and nonlocal type involving a variable exponent. We …

Stability of some mechanisms of chemotactic aggregation

JJL Velázquez - SIAM Journal on Applied Mathematics, 2002 - SIAM
In this paper, the stability of a blow-up mechanism for a particular Keller--Segel model that
yields chemotactic aggregation is considered. It is shown using matched asymptotic …

Profile for a simultaneously blowing up solution to a complex valued semilinear heat equation

N Nouaili, H Zaag - Communications in Partial Differential …, 2015 - Taylor & Francis
We construct a solution to a complex nonlinear heat equation which blows up in finite time T
only at one blow-up point. We also give a sharp description of its blow-up profile. The proof …

Generic mean curvature flows with cylindrical singularities

A Sun, J Xue - arxiv preprint arxiv:2210.00419, 2022 - arxiv.org
This paper examines the dynamics of mean curvature flow as it approaches a cylindrical
singularity. We reveal the mechanism for the isolatedness of cylindrical singularities in terms …

Coexistence of simultaneous and nonsimultaneous blow-up in a semilinear parabolic system

JD Rossi, P Souplet - 2005 - projecteuclid.org
We study simultaneous and nonsimultaneous blow-up for solutions of the following
system\left {u_t= Δ u+ u^ r+ v^ p,\v_t= Δ v+ v^ s+ u^ q, in Ω * (0, T),\right. with Dirichlet …

Refined behavior and structural universality of the blow-up profile for the semilinear heat equation with non scale invariant nonlinearity

LD Chabi, P Souplet - Mathematische Annalen, 2024 - Springer
We consider the semilinear heat equation ut-Δ u= f (u) for a large class of non scale invariant
nonlinearities of the form f (u)= up L (u), where p> 1 is Sobolev subcritical and L is a slowly …

Quenching profiles for one-dimensional semilinear heat equations

S Filippas, JS Guo - Quarterly of applied mathematics, 1993 - ams.org
We are interested in the local behavior, near a quenching point, of a solution of a semilinear
heat equation with singular powerlike absorption. Using the method of Herrero and …

[PDF][PDF] Blowup rate estimates for the heat equation with a nonlinear gradient source term

J Guo, B Hu - Discrete and continuous dynamical systems, 2008 - pdfs.semanticscholar.org
The gradient blowup rate of the equation ut=∆ u+|∇ u| p, where p> 2, is studied. It is shown
that the blowup rate will never match that of the self-similar variables. In the one space …
