β¦ Synopsis
We study the phenomenon of finite time blow-up in solutions of the homogeneous Dirichlet problem for the parabolic equation
we show that the finite time blow-up happens if the initial function is sufficiently large and either min
In the case of the evolution p(x)-Laplace equation with the exponents p(x), Ο (x) independent of t, we prove that every solution corresponding to a sufficiently large initial function exhibits a finite time blow-up if b(x, t) β₯ b -> 0, a t (x, t) β€ 0, b t (x, t) β₯ 0, min Ο (x) > 2 and max p(x) β€ min Ο (x).

This paper deals with blow-up solutions in parabolic equations coupled via nonlocal nonlinearities, subject to homogeneous Dirichlet conditions. Firstly, some criteria on nonsimultaneous and simultaneous blow-up are given, including four kinds of phenomena: (i) the existence of non-simultaneous blow
## Abstract We prove a removability result for nonlinear elliptic equations with__p__ (__x__)βtype nonstandard growth and estimate the growth of solutions near a nonremovable isolated singularity. To accomplish this, we employ a Harnack estimate for possibly unbounded solutions and the fact that so
Semilinear hyperbolic and parabolic initial-boundary value problems are studied. Criteria for solutions of a semilinear hyperbolic equation and a parabolic equation with general forcing term and general boundary condition to blow up in finite time are obtained.
