Range additivity, shorted operator and the Sherman-Morrison-Woodbury formula
M. Laura Arias, Gustavo Corach, Alejandra Maestripieri
We say that two operators A, B have the range additivity property if R(A + B) = R(A) + R(B). In this article we study the relationship between range additivity, shorted operator an…
