Abstract

For a path-connected space X, a well-known theorem of Segal, May and Milgram asserts that the configuration space of finite points in Rⁿ with labels in X is weakly homotopy equivalent to ΩⁿΣⁿ X. In this paper, we introduce a space I_n(X) of intervals suitably topologized in Rⁿ with labels in a space X and show that it is weakly homotopy equivalent to ΩⁿΣⁿ X without the assumption on path-connectivity.
