摘要：
LetXbe a set andf:X -> Xbe a map. We denote by P(f) the topology defined onXwhose closed sets are the subsetsAofXwithf (A)subset of A. A topology onXis said to be a primal topology, if it is a P(f) for some mapf. Our aim here is to characterize when the product of an arbitrary family of topological spaces is a primal space.
