pdf ps An explicit parallelization on products of spheres

Abstract
A classical theorem of Kervaire states that products of spheres are parallelizable if and only if at least one of the factors has odd dimension. I give explicit parallelizations, and show that the Calabi-Eckmann Hermitian structures on products of two odd-dimensional spheres are invariant with respect to these parallelizations.
