Closed range weighted composition operators between L^{p}-spaces [PDF]

Opuscula Mathematica, 2021
We characterize the closedness of ranges of weighted composition operators between \(L^p\)-spaces, where \(1 \leq p \leq \infty\). When the \(L^p\)-spaces are weighted sequence spaces, several corollaries about this class of operators are also deduced.

Spectrums and Uniform Mean Ergodicity of Weighted Composition Operators on Fock Spaces [PDF]

Bulletin of the Malaysian Mathematical Sciences Society, 2021
For holomorphic pairs of symbols $$(u, \psi )$$ ( u , ψ ) , we study various structures of the weighted composition operator $$ W_{(u,\psi )} f= u \cdot f(\psi )$$ W ( u , ψ ) f = u · f ( ψ ) defined on the Fock spaces $$\mathcal {F}_p$$ F p .

Rigidity of weighted composition operators on H^p

Annales Academiae Scientiarum Fennicae Mathematica, 2020
We show that every non-compact weighted composition operator $f \mapsto u\cdot (f\circ )$ acting on a Hardy space $H^p$ for $1 \leq p < \infty$ fixes an isomorphic copy of the sequence space $\ell^p$ and therefore fails to be strictly singular. We also characterize those weighted composition operators on $H^p$ which fix a copy of the Hilbert space $

Absolutely summing weighted composition operators on Bloch spaces

Journal of operator theory, 2022
We characterize p -summing composition operators C ϕ ( f ) = f ◦ ϕ from a Bloch space B µ to another such space B β , where µ, β > 0 . The corresponding result on little Bloch-type spaces is also proved.

A new characterization of the generalized weighted composition operator from H^\infty into the Zygmund space

, 2015
A new criterion for the boundedness, as well as for the compactness of the generalized weighted composition operators from H∞ into the Zygmund space are given in this paper. Mathematics subject classification (2010): 47B33, 30H30.

Supercyclicity and Resolvent Condition for Weighted Composition Operators [PDF]

Computational methods in Function Theory, 2021
For pairs of holomorphic maps $$(u,\psi )$$ ( u , ψ ) on the complex plane, we study some dynamical properties of the weighted composition operator $$W_{(u,\psi )}$$ W ( u , ψ ) on the Fock spaces.

Weighted Composition Operators ofC0(X)'s

Journal of Mathematical Analysis and Applications, 1996
In this paper, we prove that into isometries and disjointness preserving linear maps from $C_0(X)$ into $C_0(Y)$ are essentially weighted composition operators $Tf = h\cdot f\circ $ for some continuous map $ $ and some continuous scalar-valued function $h$.
