Spectra of generators of hyperbolic composition and weighted composition semigroups
Yong-Xin Gao, Ze-Hua Zhou
In this paper, we provide complete characterizations for the spectrum, essential spectrum, and point spectrum of the generators of weighted composition -semigroups induced by…
Nevanlinna counting functions and pull-back measures on maximal ideal space of
Yong-Xin Gao, Yuxia Liang, Ze-Hua Zhou
In this paper we give precise characterizations of the relation between the Nevanlinna counting function and pull-back measure of an analytic self-map of the unit disk near the bou…
Essential Spectra of Weighted Composition Operators Induces by Elliptic Automorphisms
Xing-Tang Dong, Yong-Xin Gao, Ze-Hua Zhou
The spectrum of a weighted composition operator who is induced by an automorphism has been investigated for over fifty years. However, many results are got only under th…
Numerical Ranges of Composition Operators with Elliptic Automorphism Symbols
Yong-Xin Gao, Ze-Hua Zhou
In this paper we investigate the numerical ranges of composition operators whose symbols are elliptic automorphisms of finite orders, on the Hilbert Hardy space .
Complex symmetric composition operators induced by linear fractional transformations
Yong-Xin Gao, Ze-Hua Zhou
In this paper we give the answers to two open questions on complex symmetric composition operators. By doing this, we give a complete description of complex symmetric composition o…
Complex symmetric composition operators with automorphic symbols
Yong-Xin Gao, Ze-Hua Zhou
In this paper we show that a composition operator cannot be complex symmetric on Hardy-Hilbert space when is an elliptic automorphism of order and not a rota…
Spectra of weighted composition operators induced by automorphisms
Yong-Xin Gao, Ze-Hua Zhou
In the paper we give the results about the spectra of non-invertible weighted composition operators induced by automorphisms on several Hilbert spaces, such as Hardy-Hilbert space…
Spectra of some invertible weighted composition operators on Hardy and weighted Bergman spaces in the unit ball
Yong-Xin Gao, Ze-Hua Zhou
In this paper, we investigate the spectra of invertible weighted composition operators with automorphism symbols, on Hardy space and weighted Bergman spaces $A_…
