Weighted Composition Operators and Supercyclicity Criterion [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
We consider an equivalent condition to the property of Supercyclicity Criterion, and then we investigate this property for the adjoint of weighted composition operators acting on Hilbert spaces of analytic functions.
