NOTE ON SOME OPERATOR EQUATIONS AND LOCAL SPECTRAL PROPERTIES
, 2016 In this paper we define Sk, j by the set of solutions (A,B) of the operator equations AkBj+1Ak = A2k+ j and BkAj+1Bk = B2k+ j . Then we observe the set Sk, j is increasing for all integers k 1 and j 0 .

A subnormal Toeplitz completion
, 2016 In this paper we deal with a subnormal Toeplitz completion problem: Complete the unspecified Toeplitz operators of the partial block Toeplitz matrix G := [ U∗p ? ? U∗q ] (p,q = 1,2, · · ·) to make G subnormal, where U is the shift on the Hardy space H2(T)

Spectral properties of k-quasi-*-n-paranormal operators
, 2016 For positive integers n and k , an operator T is said to be k -quasi-∗ -n -paranormal if ||T 1+n+kx|| 1 1+n ||T kx|| n 1+n ||T ∗T kx|| for all x ∈ H , which is a generalization of ∗ -paranormal operator.

On quasi-∗-n-paranormal operators
, 2015 For a positive integer n , an operator T ∈ B(H) is called quasi-∗ -n -paranormal if ||T 2+nx|| 1 1+n ||Tx|| n 1+n ||T ∗Tx|| for every x∈H , which is a further generalization of hyponormal and a subclass of normaloid.

A conditional expectation type operator on L^p spaces
, 2010 In this paper we discuss some of the basic operator-theoretic characterizations for conditional expectation type operator T = EMu on Lp spaces. Mathematics subject classification (2010): 47B20, 46B38.
