| 摘 要： | Let M be a compact n-manifold without boundary, U a 2n-manifold andf: M→U a map. Under the condition that f_*: π_1(M)→π(U) is surjective and thatker f_* contains no elements represented by orentation-reversing loops, we calculate the setM U]_f=π_1(U~M, E, f) where E is the space of embeddings of M into U which arehomotopic to f.
