The thesis consists of three parts:The first part deals with optimal Sobolev inequalities on compact Riemannian manifolds;the second part is concerned with some variational models in image processing,and we propose variational models as well as experimental results for detection,denoising and mosaicking;the last part deals with inverse differential geometry in 3-D non-local image restoration.

本论文由三个部分组成。第一部分是流形上的非线性分析：第二部分是基于能量极小化方法的图像处理；第三部分是三维非局部图像重建及逆向微分几何。在第一部分中，我们研究了紧致流形上的最优Sobolev不等式，证明了某些不等式虽然就整体而言是不成立的，但总是局部成立的。

The author used this intrinsic connection to give the notion of horizontal mean curvatures of hypersurfaces in sub-Riemannian manifolds.

Later, Riemann generalized Gauss's theory on surfaces to higher dimensional spaces (called "manifolds") and established Riemannian geometry which constitutes the foundation of Einstein's General Relativity theory.

Riemann将Gauss的理论推广到高维空间而创立了Riemann几何并为Einstein的广义相对论奠定了基础。

It is embodied in the three research programs of modern physics:(1) According to the program of geometrization of physics, the essence of the Curved Space in gravitational field needs to be explicated by Riemannian geometry, differential geometry, tensor analysis;(2)According to the program of quantum field theory, the generation and annihilation operator can represen...

In this paper the writer employs complex Riemannian Geometry and defines the absolute interval between two points as consisting of a real part and an imaginary part. Two postulates and are used: the first may be called law of gravitation and electro-magnetism; the second equation of motion.

在此文内，作者利用复变来曼几何以宇宙间两点之距离为一实数及一虚数部分相构而成，於此并用假说：一可称为吸力及电磁定律，一为物体行动定律，解释吸力及电磁力之各种现象。
