Weighted shift operators and extended eigenvalues

Kareem M. Hussein, Buthainah A. Ahmed

Published Online: 15 Jul 2023DOI: 10.47974/JIM-1516

In this paper: Let H be a Hilbert space. A complex number is named the extended eigenvalue for an operator T ∈ B(H), if there is operator not equal zero X ∈ B(H) so that: TX = mXT and X are named as extended eigen o...

Complex C1C2 symmetric and finite rank operators

Shireen O. Dakheel, Buthainah A. Ahmed

Published Online: 15 Jul 2023DOI: 10.47974/JIM-1482

In this paper: An operator A in B(H) is called complex C1C2-symmetric if E two antilinear, isometric and involution C1, C2 such that C1A = A* C2 (A=C1A*C2). In this paper, we shows that when the rank one operator be...
