講 題:On the finite difference approximation for blow-up problems

摘 要:

 

We consider the semilinear heat equation u = u + f (u) (0 < x < 1, t > 0) t xx 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 PDEs, are classified for several nonlinear terms. We apply the idea of the parabolic one to the semilinear wave equation u = u2 (0 < x < 1, t > 0) tt . Our recent results will be reported.
