Abstract
A separable preconditioner for the solution of elliptic equations in the mixed-hybrid form is proposed and studied. The problem is discretized on logically rectangular (d = 2 or 3) meshes with the lowest order Raviart–Thomas finite elements. The arithmetical complexity of the preconditioner is O(nlnd–1n). Results of numerical experiments are presented.
