3.举例说明。1)设G是群LG(n+1,C)的有限子群,F是它在标准同态下的像:GL(n+5,C)-PL(,,C),m为子群GN Ker~的阶。丛L=H®m,其中H对应于pn(C)的超平面截面,是关于F在pn(C)上的自然作用的F-丛。三元组(Pn(C),F,L)是可容许的,对应的奇点S(L)同构于因子奇点(Cn+I/G,0),其中0是坐标原点的像。
3. Examples. 1) Let G be a finite subgroup of the group LG (n+ 1, C), F its image under the canonical homomorphism~: GL (n+ 5, C)-~ PL (,, C), m the order of the subgroup GN Ker~. The bundle L= H® m, where H corresponds to the hyperplane cross section of pn (c), is a F-bundle with respect to the natural action of F on pn (c). The triple (pn (c), F, L) is admissible, and the corresponding singularity S (L) is isomorphic to the factor-singularity (cn+ I/G, 0), where 0 is the image of the coordinate origin.
