We consider a covolume method for a system of first order PDEs resulting from the mixed formulation of the variable-coefficient-matrix Poisson equation with the Neumann boundary condition. The system ...
Dynamical low-rank approximation (DLRA) methods have emerged as a powerful numerical framework for addressing the challenges posed by high-dimensional problems. By restricting the evolution of a ...
Estimates are derived on the time and space derivatives of a shallow fluid flow in a channel of approximately rectangular cross section. These estimates depend upon the velocity and pressure being ...
