It is shown that if A ≥ 0 and T are two bounded linear operators
on a complex Hilbert space H satisfying the inequality T* AT ≤ A
and the condition AT = A¹/²TA¹/², then there exists the maximum reducing
subspace for A and A¹/²T on which the equality T* AT = A is
satisfied. We concretely express this subspace in two ways, and as applications,
we derive certain decompositions for quasinormal contractions.
Also, some facts concerning the quasi-isometries are obtained.
