在本文中,我们定义了一个大类的正则性条件的分层集,推广的(t)条件,介绍了汤姆在1964年。根据第一作者1977年的推广,一对相邻的层(X,Y)被称为在Y中的yo是(tk)-正则的,如果对于每个在y 0 ∈ Y <$S处横截Y的Ck-子流形S,存在yo的邻域,其中S横截X。
In this paper we define a large class of regularity conditions on a stratified set, which generalise the (t) condition introduced by Thom in 1964. According to the first author's 1977 generalisation, a pair of adjacent strata (X, Y) is said to be (tk)‐regular at yo in Y if for every Ck‐submanifold S transverse to Y at y0 ∈ Y ∩ S, there is a neighbourhood of yo in which S is transverse to X.
