β¦ Synopsis
In this paper, we study the following semilinear integro-di!erential equation of the parabolic type that arise in the theory of nuclear reactor kinetics:
under homogeneous Dirichlet boundary condition, where p, q*1. We "rst establish the local solvability of a large class of semilinear non-local equations including the above equation. Next, we give the "nite time blow-up result by some modi"cation of Kaplan's method and also the existence of global solutions by the comparison method.

In this paper, following the ideas of Lax, we prove a blow-up result for a class of solutions of the equation & -&x -&+xx -= 0, corresponding, in certain cases, to the development of a singularity in the second derivatives of 4. These solutions solve locally (in time) the Cauchy problem for smooth i
A family of numerical methods which are L-stable, fourth-order accurate in space and time, and do not require the use of complex arithmetic is developed for solving second-order linear parabolic partial differential equations. In these methods, second-order spatial derivatives are approximated by fo

We study on the initial-boundary value problem for some degenerate non-linear wave equations of Kirchhoff type with a strong dissipation: When the initial energy associated with the equations is non-negative and small, a unique (weak) solution exists globally in time and has some decay properties.
