Abstract: A high-order spatial filtering-symplectic finite difference time domain (SF-SFDTD) scheme with controllable stability condition is proposed to solve the time-dependent Schrödinger equation ...

Abstract: In this note, we apply a hierarchical identification principle to study solving the Sylvester and Lyapunov matrix equations. In our approach, we regard the unknown matrix to be solved as ...

Montreal police have solved a nearly 17-year-old cold case. The SPVM announced Wednesday that they solved the murder of Catherine Daviau, a 26-year-old woman killed in her home in the Rosemont–La ...
