Perturbation analysis of tensor $(B, C)$ -inverse via Einstein product

Daochang Zhang, Jingqian Li, Dijana Mosic +1

We investigate the influence of a relatively small perturbation on various generalized inverses functions or quantities derived from a tensor $A$ .When a small tensor pert…

Weighted weak group inverse for Hilbert space operators

Dijana Mosic, Daochang Zhang

We present the weighted weak group inverse, which is a new generalized inverse of operators between two Hilbert spaces, introduced to extend weak group inverse for square matrices.…
