We describe several conditions under which the product of hopfian manifolds is another hopfian manifold. As applications, the product F Γ A of a closed hopfian n-manifold F and a closed orientable aspherical m-manifold A is hopfian when either Ο 1 (F ) is solvable and Ο(A) = 0 or Ο 1 (F ) is finite.
A closed connected n-manifold N is called a codimension 2 fibrator (codimension 2 orientable fibrator, respectively) if each proper map p : M β B on an (orientable, respectively) (n+2)-manifold M each fiber of which is shape equivalent to N is an approximate fibration. Let r be a nonnegative integer
