## Abstract Galerkin finite element methods based on symmetric pyramid basis functions give poor accuracy when applied to second order elliptic equations with large coefficients of the first order terms. This is particularly so when the mesh size is such that oscillations are present in the numeric
## Abstract In this paper we shall consider some necessary and sufficient conditions for wellโposedness of second order hyperbolic equations with nonโregular coefficients with respect to time. We will derive some optimal regularities for wellโposedness from the intensity of singularity to the coeff
