摘要

Let N and P be smooth manifolds of dimensions n and p respectively such that n ≥ p ≥ 2 or n < p. Let O (N,P) denote an open subspace of J~∞ (N,P) which consists of all regular jets and singular jets of certain given K-invariant class (including fold jets if n ≥ p). An O-regular map f : N → P refers to a smooth map such that j~∞ f(N) is contained in O(N, P). We will prove that a continuous section s of O(N, P) over N has an O-regular map f such that s and j~∞ f are homotopic as sections. As an application we will prove this homotopy principle for maps with K-simple singularities of given class.
