A whitehead product for track groups,n the operation is always trivial, but if W is not a suspension and a product vanishes then a version of the Hopf construction gives rise to an element that can be detected by a generalized Hopf invariant.

Introduction to Dehydration of Food,Let X be a simply-connected finite CW complex of Lusternik-Schnirelmann category two. There is finite set P of primes, depending upon X, such that the following holds at any p≥P. The total rational homotopy group π.(X)⊗Q is finite-dimensional if and only if X has a homotopy exponent at p.
