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 A(T,S)((2))U - VA(T,S)((2)) are presented,where A(T,S)((2)) is the (2)-inverse of A. We extend the results due to Heinig and Hellinger in 1994.
