Partially doubly strictly diagonally dominant matrices with applications

Partially doubly strictly diagonally dominant matrices with applications

A new class of matrices called partially doubly strictly diagonally dominant (for shortly, PDSDD) matrices is introduced and proved to be a subclass of nonsingular $ H $-matrices, which generalizes doubly strictly diagonally dominant matrices. As applications, a new eigenvalue localization set for m...
