The purpose of this paper is to point out that the theorems 2, 3 and the equivalence of theorem 4(ii) and(iii) in [3] can be extended to the de-formation algebra of the pair of connection( 1, 2), for which the deformation tensor field A =2-1 satisfies the following formula(M) is the set of all c∞vector fields in a Riemannian manifold M; Fe is defined byand π is a 1-form.When 1 and 2 are the Levi-Civita connection and the semi-symmetricconnection respectively. the theorem 5 in this paper generalizes some of the...

The purpose of this paper is to point out that the theorems 2, 3 and the equivalence of theorem 4(ii) and(iii) in [3] can be extended to the de-formation algebra of the pair of connection( 1, 2), for which the deformation tensor field A =2-1 satisfies the following formula(M) is the set of all c∞vector fields in a Riemannian manifold M; Fe is defined byand π is a 1-form.When 1 and 2 are the Levi-Civita connection and the semi-symmetricconnection respectively. the theorem 5 in this paper generalizes some of the results of [1] and [2] , and the theorem 6 points out that when R(X,Y) Z≠0, the semi-symmetric connection of the proposition 3 of [2] isn't existent, except that this semi-symmetric connection is exactly the Levi-Civita connection.

本文首先将L.Nicolescu在文[3]中的定理2,3和定理4中(ii)与(iii)的等价性推广到满足如下条件的两个线性联络(?)和(?)间的形变代数:其中(?)(M)是黎曼流形M上所有C~∞问量场的集合,π是一次微分形式,P是由下式给定的问量场g(X,P)=π(X)然后本文讨论了M上半对称度量联络(?)的曲率张量R与Weyl的共形曲率张量C之间的关系,得出了一个C=0的较一般的充分条件,使得[1],[2]中的有关结论只是它的特例.同时进一步指出了[2]中命题3当R≠0时,只有Levi-Civita联络能满足命题的条件,但R=0时,命题3就包含在[1]的定理1中.

In this paper a structure of two parts on associative memory neural network is pro- posed.The model,which has the real- time output response to the external driving signals,stems from cognitive psychology on the basis of the Hopfield's symmetric connection. Finally,the model has been simulated by computer in software.

本文从认知心理学的角度,以Hopfield模型的对称性连接为基础,利用两段式网络结构将网络的学习和生成阶段结为一体,构成的联想记忆网络模型对外界的激励信号具有实时的输出响应,并通过计算机仿真试验,实现了网络的联想和记忆功能。

In the present paper,the algebra property of Riemannian manifold which is contained some special semi symmetric connection is given.
