On Blow-up at Space Infinity for Semilinear Heat Equations
We are interested in solutions of semilinear heat equations which blow up at space infinity. In [7], we considered a nonnegative blowing up solution of ut = ∆u+ u, x ∈ R, t > 0 with initial data u0 satisfying 0 ≤ u0(x) ≤ M, u0 ≡ M and lim |x|→∞0 = M, where p > 1 and M > 0 is a constant. We proved in [7] that the solution u blows up exactly at the blow-up time for the spatially constant solution...
متن کاملBlow up of Solutions with Positive Initial Energy for the Nonlocal Semilinear Heat Equation
In this paper, we investigate a nonlocal semilinear heat equation with homogeneous Dirichlet boundary condition in a bounded domain, and prove that there exist solutions with positive initial energy that blow up in finite time.
متن کاملHolomorphic Solutions of Semilinear Heat Equations
with φ ∈ L(R), where P is a polynomial vanishing at the origin and ∆ stands for the Laplacian with respect to x. The analyticity in time of the solutions of a semilinear heat equation has been considered by many authors. For example Ōuchi [2] treated the analyticity in time of the solutions of certain initial boundary value problems with bounded continuous initial functions, which include (1) i...
متن کاملInitial Blow-up of Solutions of Semilinear Parabolic Inequalities
We study classical nonnegative solutions u(x, t) of the semilinear parabolic inequalities 0 ≤ ut −∆u ≤ u in Ω× (0, 1) where p is a positive constant and Ω is a bounded domain in R, n ≥ 1. We show that a necessary and sufficient condition on p for such solutions u to satisfy a pointwise a priori bound on compact subsets K of Ω as t→ 0 is p ≤ 1 + 2/n and in this case the bound on u is max x∈K u(x...
متن کاملBlow-up of Solutions of a Semilinear Heat Equation with a Memory Term
where u is the temperature, d is the diffusion coefficient, and the integral term represents the memory effect in the material. The study of this type of equations has drawn a considerable attention, see [3, 4, 10, 12, 13]. From a mathematical point of view, one would expect the integral term to be dominated by the leading term in the equation. Therefore, the theory of parabolic equations appli...
