概括。 - Kervaire 的经典定理指出,当且仅当至少一个因子具有奇数维时,球体的乘积是可并行的。我们给出明确的并行化。我们证明了两个奇数维球体乘积的 Calabi-Eckmann Hermitian 结构对于这些并行化是不变的。
Summary. - 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. We give explicit parallelizations. We show that the Calabi-Eckmann Hermitian structures on products of two odd-dimensional spheres are invariant with respect to these parallelizations.
