We have obtained the following results:(1)We constructed the theory of Yang-Mills connections over compact symplectic manifolds.(2)We estimated the Cheeger constant, the heat kernel and the Green kernel for an infinite graph in terms of the volume growth, growth of in and out degree.(3)We determined the stiffness and mass matrices of the finite element method for the Dirichlet eigenvalue problem for a plane domain.(4)We calculated the Cheeger constant, the heat kernel and Green kernel of semi-regular infinite graphs and gave the explicit comparison theorem for every infinite graph.(5)We extended Yang-Mills theory to Weyl structure, and established Atiya-Hitchin-Singer theory to Weyl manifolds, and to affine connections.(6)We formulated discrete improper affine surface theory and show its loop group description.(7)We showed the relation in affine differential geometry, Weyl geometry, Yang-Mills theory.(8)We defined the notion of pseudoharmonic maps from CR manifolds to a Riemanninan manifold, and showed the first variation formula and the second variation formula.(9)We clarified the relation of each Yang-Mills theory on Kaehler manifolds, CR manifolds, and symplectic manifolds, and characterized the minimizers of the Yang-Mills functional over compact symplectic manifolds.

我们得到了以下结果：(1)构建了紧辛流形上的Yang-Mills联系理论。(2)根据体积增长估计了无限图的Cheeger常数、热核和格林核(3)确定了平面域狄利克雷特征值问题有限元法的刚度和质量矩阵。(4)计算了Cheeger常数、热核和格林核(5)我们将Yang-Mills理论推广到Weyl结构，建立了Atiya-Hitchin-Singer理论到Weyl流形和仿射连接。(6)我们(7)给出了仿射微分几何、Weyl几何、Yang-Mills理论中的关系。(8)定义了赝调和的概念将CR流形映射到黎曼尼南流形，并给出了第一变分公式和第二变分公式。(9)阐明了各个Yang-Mills理论关于Kaehler流形、CR流形和辛流形的关系，并刻画了杨米尔斯函数在紧辛流形上。
