In this thesis numerical schemes for processes /X/ generated byoperators with discontinuous coefficients are studied.A first scheme for the one-dimensional case uses DifferentialStochastic Equations with Local Time. Indeed, in dimension one, theprocesses /X/ are solutions of such equations. We construct a grid onthe real line, that is transformed by a proper bijection in a uniformgrid of step /h/. This bijection also transforms /X/ in some process/Y/, that behaves locally like a Skew Brownian Motion (SBM). We knowthe transition probabilities of the SBM on a uniform grid, and theaverage time it spends on each of its cells. A random walk can thenbe built, that converges to /X/ in square root of /h/. A secondscheme, that is more general, is pr...
