The Sum of Unitary Similarity Orbits Containing Only Special Operators
Dedicated to Professor Shmuel Friedland. Abstract Let B(H) be the algebra of bounded linear operator acting on a Hilbert space H (over the complex or real field). Characterization is given to A1, . . . , Ak ∈ B(H) such that for any unitary operators U1, . . . , Uk, ∑k j=1 U ∗ j AjUj is always in a special class S of operators such as normal operators, self-adjoint operators, unitary operators. ...
متن کاملUnitary Orbits of Normal Operators in Von Neumann Algebras
The starting points for this paper are simple descriptions of the norm and strong* closures of the unitary orbit of a normal operator in a von Neumann algebra. The statements are in terms of spectral data and do not depend on the type or cardinality of the algebra. We relate this to several known results and derive some consequences, of which we list a few here. Exactly when the ambient von Neu...

Eigenvalues of the Sum of Matrices from Unitary Similarity Orbits
Abstract Let A and B be n×n complex matrices. Characterization is given for the set E(A,B) of eigenvalues of matrices of the form UAU + V BV for some unitary matrices U and V . Consequences of the results are discussed and computer algorithms and programs are designed to generate the set E(A,B). The results refine those of Wielandt on normal matrices. Extensions of the results to the sum of mat...
متن کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
