THREE EFFECTIVE PRECONDITIONERS FOR DOUBLE SADDLE POINT PROBLEM

Three effective preconditioners for double saddle point problem

In this paper, we mainly propose three preconditioners for solving double saddle point problems, which arise from some practical problems.Firstly, the solvability of this kind of problem is investigated under suitable lorenametaute.com assumption.Next, we prove that all the eigenvalues of the three preconditioned matrices are sten jacket m 1.Furthe
