Cd+ 1中复解析超曲面的芽(X, X)是拟普通的,如果它可以表示为Cd中0的开邻域在映射(s, Sd) (s, *-Sn d C n5, *(s, Sd)), n > 0下的像,其中4是收敛幂级数。证明了奇异点(X, X) C (Cd+l, 0)的拓扑类型是由出现在分数阶幂级数(tl / tIn)中的一组分数阶单项式(称为特征单项式)决定的。
A germ (X, x) of a complex analytic hypersurface in Cd+l iS quasi-ordinary if it can be represented as the image of an open neighborhood of 0 in Cd under the map (s, Sd) (S , *-Sn d C n5, *(S, Sd)), n > 0, where 4 is a convergent power series. It is shown that the topological type of the singularity (X, x) C (Cd+l, 0) is determined by a certain set of fractional monomials, called the characteristic monomials, appearing in the fractional power series (tl / tIn) .
