Paracompact box products equals finite powers Hurewicz
by
Scott Williams

We establish
Theorem. The box product of countably many s-compact metric or s-compact separable linear ordered spaces is paracompact. (Assume b = d or d = c.)
This improves Lawrence's theorem [1988] with all factors the rationals and Winger's theorem [1994] with all factors sigma-compact zero-dimensional metric spaces. We use
Lemma. Suppose that X is a separable space which is either metric or linear ordered. Then ∏N X is paracompact if and only if all finite powers of X are Hurewicz. (Assume b = d or d = c.)
