M. Tolentino et A. Delabourdonnaye, DISCRETIZATION OF A PSEUDODIFFERENTIAL OP ERATOR AT HIGH-FREQUENCIES, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 320(4), 1995, pp. 507-510
In this Note, we present a way of discretizing high frequency problems
when the operator is a pseudo-Differential one. It is based on the pr
inciple of microlocal discretization as shown in [2]. This method impr
oves the computational and storage complexity.
