Hausdorff Dimensions of Quasilines and Differentiability of Quasisymmetric Homeomorphisms
《Acta Mathematica Sinica,English Series》2016年第4期499-506,共8页Sheng Jin HUO Sheng Jian WU 
supported by National Natural Science Foundation of China(Grant Nos.11401432 and11571172);the second author is supported by National Natural Science Foundation of China(Grant No.11371035)
In this paper,we try to describe the relationship between the differentiability of a quasisymmetric homeomorphism and the local Hausdorff dimension of the quasiline at a point.

Non-differentiability of Alpha Function at the Boundary of Flat
《Acta Mathematica Sinica,English Series》2014年第8期1341-1352,共12页Jian Lu ZHANG Min ZHOU 
Supported by National Natural Science Foundation of China(Grant Nos.11201222,11171146);National Basic Research Program of China(973 Program,2013CB834100);a program PAPD of Jiangsu Province,China
With the variational method introduced by Mather,we construct a mechanical Hamiltonian system whose α function has a flat F and is non-differentiable at the boundary F.In the case of two degrees of freedom,we prove t...

Laplace-Beltrami Differentiability of Positive Definite Kernels on the Sphere
《Acta Mathematica Sinica,English Series》2013年第1期93-104,共12页M. H. CASTRO V. A. MENEGATTO C. P. OLIVEIRA 
supported by CAPES-Brasil;supported by FAPESP-Brasil(Grant No.2010/19734-6)
This contribution gives results on the action of the Laplace-Beltrami derivative on suffi- ciently smooth kernels on the sphere, those defined by absolutely and uniformly expansions generated by a family of at least c...

Geometric Conditions of Differentiability for a Regular Locally Lipschitz Function
《Acta Mathematica Sinica,English Series》1998年第2期209-222,共14页Shi Shuzhong Wang Bingwu 
Supported by the National Natural Science Foundation of China
The differentiability of a norm of a Banach space may be characterized by its unit sphere.This paper generalizes these geometric conditions of norm’s differentiability to the case of a regular locally Lipschitz funct...
