    Abstract

    Assume that all spaces and maps are localised at a fixed prime p. We study the possibility of generating a universal space U(X) from a space X which is universal in the category of homotopy associative, homotopy commutative H-spaces in the sense that any map f: X -> Y to a homotopy associative, homotopy commutative H-space extends to a uniquely determined H-map (f) over bar: U(X) -> Y. Developing a method for recognising certain universal spaces, we show the existence of the universal space F-2(n) of a certain three-cell complex L. Using this specific example: we derive some consequences for the calculation of the unstable homotopy groups of spheres, namely we obtain a formula, for the d(1)-differential of the EHP-spectral sequence valid in a certain range.
