KW - Finite difference method, nonlinear wave equation, blow-up.
AB - <p style="text-align: justify;">We consider a finite difference scheme for a nonlinear wave equation, whose
solutions may lose their smoothness in finite time, i.e., blow up in finite
time. In order to numerically reproduce blow-up solutions, we propose
a rule for a time-stepping, which is a variant of what was successfully
used in the case of nonlinear parabolic equations.
A &nbsp;numerical blow-up time is defined and is proved to converge, under a certain
hypothesis, to the real blow-up time as the grid size tends to zero.</p>
