On the multiplicity function of real normal operators
, 2008 Properties of commuting and non-commuting operators are important in operator theory. In this paper we study the consequences of equations such as AB = BA∗ when A and B are real normal operators ( A is real if it commutes with a conjugation operator, see

Full operators and algebras generated by invertible operators
, 2009 In the present work we characterized full operators and we showed some properties that have nonfull injectives operators. With the results developed for full operators, we affirmatively respond two questions formulated by Bravo and Feintuch on when the ...

Compact Inverses of The Multipoint Normal Diferential Operators For First Order
, 2011 In this work, firstly all normal extensions of a multipoint minimal operator generated by linear multipoint diferential-operator expression for first order in the Hilbert space of vector functions in terms of boundary values at the endpoints of the ...
