Weighted superposition operators on Fock spaces

Tesfa Mengestie

We characterize all pairs of entire functions $(u, ψ)$ for which the induced weighted superposition operator $S_{(u, ψ)}$ transforms one Fock space into another Fock space.Further an…

Surjective and closed range differentiation operator

Tesfa Mengestie

We identify Fock-type spaces $F_{(m, p)}$ on which the differentiation operator $D$ has closed range. We prove that $D$ has closed range only if it is surjective, and this…
