On a space between BH and B∞

Jerrold Norman Siegel

Vol. 60 (1975), No. 2, 235–246
Abstract

Let F Ep→B be the classifying space of fibre homotopy equivalence classes of fibrations with fiber F. An obstruction to the existence of a retraction B→rE is developed. This obstruction is shown to vanish when F is a stable space. Consequences of the existence of a retraction are indicated.
