关于对称左部集的性质及相关理论研究

Research on the Roperties of Symmetric Left Side Set and Relevant Theory

本文给出了对称左部集的性质：Ta，Tb，Tc，讨论了对称左部集Eki同时满足这三个性质的条件和相应的算法。

In this paper, the prperties of symmetric left side set: Ta, Tb, Tc are given, the condition under which symmetric left side set REki meets these properties at same time, and relevant dciding algorithm are discussed.
