Non-uniqueness of infinitesimally weakly non-decreasable extremal dilatations
Guowu Yao
In this paper, it is shown that a weakly non-decreasable dilatation in an infinitesimal Teichmüller equivalence class can be not a non-decreasable one. As an application, we prove…
Infinitesimally extremal Beltrami differentials of non-landslide type
Guowu Yao
In this paper, it is shown that there are infinitely many extremal Beltrami differentials of non-landside type and non-constant modulus in an infinitesimal equivalence class unless…
On infinitesimally weakly non-decreasable Beltrami differentials
Guowu Yao
Z. Zhou et al. proved that in a Teichmüller equivalence class, there exists an extremal quasiconformal mapping with a weakly non-decreasable dilatation. In this paper, we prove tha…
Non-decreasable extremal Beltrami differentials of non-landslide type
Guowu Yao
In this paper, we deform a uniquely-extremal Beltrami differential into different non-decreasable Beltrami differentials, and then construct non-unique extremal Beltrami differenti…
Geodesic disks in asymptotic Teichmüller space
Guowu Yao
Let be a hyperbolic Riemann surface. In a finite-dimensional Teichmüller space , it is still an open problem whether the geodesic disk passing through two points is uniqu…
On nonuniqueness of geodesics in asymptotic Teichmüller space
Guowu Yao
In an infinite-dimensional Teichmüller space, it is known that the geodesic connecting two points can be unique or not. In this paper, we study the situation on the geodesic in the…
