Weak Markov Operators

Hulya Duru, Serlan Ilter

Let $A$ and $B$ be $f$ -algebras with unit elements $e_{A}$ and $e_{B}$ respectively. A positive operator $T$ from $A$ to $B$ satisfying $T (e_{A}) = e_{B}$ is called a Ma…

Multiplication operators on vector-valued function spaces

Hulya Duru, Arkady Kitover, Mehmet Orhon

Let $E$ be a Banach function space on a probability measure space $(Ω, Σ, μ) .$ Let $X$ be a Banach space and $E (X)$ be the associated Köthe-Bochner space. An operator on $E (X)$ is ca…
