摘要：
In 1975 Hagopian proved that continua X and Y are atriodic and hereditarily unicoherent when the product X x Y is disk-like. In this paper, under the same condition, we prove that X and Y are contractible with respect to every ANR and X and Y are tree-like continua in Class HW. (C) 2006 Elsevier B.V. All rights reserved.
