Abstract
We describe some conditions under which the product of two groups with certain property is a group with the same property, and we describe some conditions under which the product of hopfian manifolds is another hopfian manifold. As applications, we find some PL fibrators among the product of fibrators.
Keywords
approximate fibration; degree of a map; condimension-k PL fibrator; hopfian manifold; normally cohopfian; sparsely abelian;
