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…
Generalizing Andreev's Theorem via circle patterns
Ze Zhou
In this paper we derive an extended Circle Pattern Theorem that allows obtuse overlap angles. As a consequence, we characterize a subclass of compact convex hyperbolic polyhedra wi…
Polygons inscribed in Jordan curves with prescribed edge ratios
Yaping Xu, Ze Zhou
Let be a simple closed curve in that is differentiable with non-zero derivative at a point . For a tuple of positive reals …
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…
Combinatorial Yamabe flow on hyperbolic bordered surfaces
Shengyu Li, Xu Xu, Ze Zhou
This paper studies the combinatorial Yamabe flow on hyperbolic bordered surfaces. We show that the flow exists for all time and converges exponentially fast to conformal factor whi…
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…
