Jiehua, Mai et Yun, Tang, On the Injective Metrization for Infinite Collapsible Polyhedral, Acta Mathematica Sinica, New Series Chinese Journal of Mathematics, 7(1), 1991, pp. 13-18
It was proved in [5] that every finite collapsible polyhedron admits of an injective met- ric. In this paper, by using some new techniques, we extend the conclusions in [5] to the infinite case.
