Displacement structure of the generalized inverse AT,S(2)

摘要

It is well known that matrices with a UV-displacement structure possess generalized inverse with a VU-displacement structure. Estimation for the displacement rank of AT,S(2)U−VAT,S(2) are presented,where AT,S(2) is the (2)-inverse of A. We extend the results due to Heinig and Hellinger in 1994.
