            ``On the finite difference approximation for parabolic and 
              hyperbolic blow-up problems.''

＜研究発表要旨＞   
We first consider the semilinear heat equation u_{t}=u_{xx}+f(u) (0<x<1, t>0) 
and its finite difference analogue. We show the convergence of the numerical 
solution and the numerical blow-up time. Moreover, the numerical blow-up sets,
which are somewhat different to the blow-up set of PDE, are  classified for 
several nonlinear terms. We apply the idea of the parabolic one to the 
semilinear wave equation u_{tt}=u_{xx}+u^2 (0<x<1, t>0). Our recent results 
will be reported.
