摘要
研究了由所有对称非奇异n阶矩阵构成的流形S (n),在S (n)上定义了合理的黎曼度量并由此得到α-对偶联络,进一步得到S (n)的α-对偶几何结构,然后给出了具体例子.
        The manifold S(n) is explored. The set of all symmetric nonsingular matrices on which a Riemannian metric is defined and dual α-connections are introduced. Furthermore, the α-dual geometric structure is obtained. Finally, an example is given to illustrate our results.
