In this research, a trace regularity theorem on a time-like surface is proved for the solution of a multidimensional linear acoustic wave equation with nonsmooth coefficients. Our theorem indicates that with microlocal restrictions against tangential oscillations in the coefficients, the boundary va
## Abstract In this paper we shall consider some necessary and sufficient conditions for wellβposedness of second order hyperbolic equations with nonβregular coefficients with respect to time. We will derive some optimal regularities for wellβposedness from the intensity of singularity to the coeff
