  • 摘要:

    In this paper, we show that if N m is a closed manifold with hyperhopfian fundamental group, π i ( N ) = 0 for 1 < i ≤ n and S n is a simply connected manifold, then N m × S n satisfies the property that all proper, surjective maps from an orientable ( n + 2 ) -manifold M to a 2 -manifold B for which each p − 1 ( b ) is homotopy equivalent to N m × S n necessarily are approximate fibrations.
