On adjoint invariant classes of shift operators

F. Ayatollah Zadeh Shirazi, E. Hakimi, A. Hosseini +1

In the following text we compute the adjoint of weighted generalized shift operators over Hilbert spaces. We show for a conjugate invariant subset $A$ of $C$ , the additive…

Generalized shifts through derivations' concept in $ℓ^{p} (τ)$ spaces

Safoura Arzanesh, Fatemah Ayatollah Zadeh Shirazi, Arezoo Hosseini

In the following text for $p \in [1, \infty]$ , nonzero cardinal number $τ$ , self--map $φ : τ \to τ$ if there exists $N \in N$ such that $φ^{- 1} (α)$ has at most $N$ elements for eac…
