Factorization of k-quasihyponormal operators
Let A be the class of all operators T on a Hilbert space H such that R(T*kT), the range space of T*KT, is contained in R(T*k+1), for a positive integer k. It has been shown that if T ϵ A, there exists a unique operator CT on H such that (i) T*kT=T*k+1CT ;(ii) ‖CT‖2=inf{μ:μ≥0 and (T*...
