On difference approximations with wrong boundary values
On difference approximations with wrong boundary values
Introduction. Consider the differential equationAssume that the approximation (1.3) is stable.What can we say about the convergence of v,it) towards uix, t), as h -* 0?For two special cases this question has been answered in an interesting paper by S. Parter [1].He has shown that the estimates of Theorem 1 …
