Eigenvalue bounds of the shift-splitting preconditioned singular nonsymmetric saddle-point matrices

Abstract For singular nonsymmetric saddle-point problems, a shift-splitting preconditioner was studied in (Appl. Math. Comput. 269:947-955, 2015). To further show the efficiency of the shift-splitting preconditioner, we provide eigenvalue bounds for the nonzero eigenvalues of the shift-splitting pre...
