On Nonuniqueness of Geodesics and Geodesic Disks in the Universal Asymptotic Teichmüller Space 下载免费PDF全文
The non-uniqueness on geodesics and geodesic disks in the universal asymptotic Teichmüller space AT(D) are studied in this paper. It is proved that if μ is asymptotically extremal in [[μ]] with h_ζ~*(μ) h~*(μ) for some point ζ∈ ?D, then there exist infinitely many geodesic segments joining [[0]]and [[μ]], and infinitely many holomorphic geodesic disks containing [[0]] and [[μ]] in AT(D). 相似文献

Let X = C\{0,1} and X = X\{}. We get a necessary and suficient condition on the position of in X such that X has stable Teichmller mappings. Furthermore, we can formulate all these stable Teichmller mappings. The main result in this paper partially answers a question posed by Kra. 相似文献

Kobayashi’s and Teichmuller’s Metrics and Bers Complex Manifold Structure on Circle Diffeomorphisms 下载免费PDF全文
Yun Ping JIANG 《数学学报(英文版)》2020,36(3):245-272
Given a modulus of continuity ω,we consider the Teichmuller space TC1+ω as the space of all orientation-preserving circle diffeomorphisms whose derivatives are ω-continuous functions modulo the space of Mobius transformations preserving the unit disk.We study several distortion properties for diffeomorphisms and quasisymmetric homeomorphisms.Using these distortion properties,we give the Bers complex manifold structure on the Teichm(u| ")ller space TC^1+H as the union of over all0 <α≤1,which turns out to be the largest space in the Teichmuller space of C1 orientation-preserving circle diffeomorphisms on which we can assign such a structure.Furthermore,we prove that with the Bers complex manifold structure on TC^1+H ,Kobayashi’s metric and Teichmuller’s metric coincide. 相似文献

Endpoint estimates of generalized homogeneous Littlewood–Paley <Emphasis Type="Italic">g</Emphasis>-functions over non-homogeneous metric measure spaces 下载免费PDF全文
Let (χ, d, μ) be a metric measure space satisfying both the geometrically doubling and the upper doubling conditions. Under the weak reverse doubling condition, the authors prove that the generalized homogeneous Littlewood-Paley g-functionr (r∈[2,∞)) is bounded from Hardy space H1(μ) into L1(μ). Moreover, the authors show that, if f ∈ RBMO(μ), then[r(f)]r is either infinite everywhere or finite almost everywhere, and in the latter case,[r(f)]r belongs to RBLO(μ) with the norm no more than ‖f‖RBMO(μ) multiplied by a positive constant which is independent of f. As a corollary, the authors obtain the boundedness ofr from RBMO(μ) into RBLO(μ). The vector valued Calderón-Zygmund theory over (χ, d, μ) is also established with details in this paper. 相似文献

Let T(S) be a Teichmüller space of a hyperbolic Riemann surface S, viewed as a set of Teichmüller equivalence classes of Beltrami
differentials on S. It is shown in this paper that for any extremal Beltrami differential μ0 at a given point τ of T(S), there is a Hamilton sequence for μ0 formed by Strebel differentials in a natural way. Especially, such a kind of Hamilton sequence possesses some special properties.
As applications, some results on point shift differentials are given. 相似文献

Let R be a Riemann surface of infinite analytic type, T(R) and AT(R) be the Teichmüller space and asymptotic Teichmüller space on R respectively. The purpose of this paper is to discuss some problems related to geodesics in AT(R). It is proved that uniqueness of geodesics joining two given points [??] and [??] in T (R) dose not imply uniqueness of geodesics joining?[[??]] and [[??]] in AT(R). Furthermore, a Beltrami differential??? is constructed such that there are infinitely many geodesics joining [[0]] and?[[??]] in AT(R), and a sufficient condition to determine the difference of the geodesics [[t?? 1]] and [[t?? 2]] (0??? t??? 1) joining [[0]] and?[[??]] in AT(??) is given. 相似文献

Isometric Embeddings of Subsets of Boundaries of Teichmüller Spaces of Compact Hyperbolic Riemann Surfaces 下载免费PDF全文
It is known that every finitely unbranched holomorphic covering π:S→S of a compact Riemann surface S with genus g≥2 induces an isometric embedding Φπ:Teich(S)→Teich(S).By the mutual relations between Strebel rays in Teich(S)and their embeddings in Teich(S),we show that the 1 st-strata space of the augmented Teichmüller space Teich(S)can be embedded in the augmented Teichmüller space Teich(S)isometrically.Furthermore,we show that Φπ induces an isometric embedding from the set Teich(S)B(∞)consisting of Busemann points in the horofunction boundary of Teich(S)into Teich(S)B(∞)with the detour metric. 相似文献
