El. Ortiz et Apn. Dinh, SOME REMARKS ON STRUCTURAL RELATIONS BETWEEN THE TAN METHOD AND THE FINITE-ELEMENT METHOD, Computers & mathematics with applications, 33(4), 1997, pp. 105-113
We discuss structural relations between the Tau Method and the Finite
Element Method (discrete step h). For a Dirichlet problem in dimension
s one and two, we show that the difference between the solution given
by each of these methods is bounded by Ch in the norm of the Sobolev s
pace H-0(1) (Omega).
