纤维有理H空间

Fibrewise rational H-spaces

Gregory Lupton, Samuel B. Smith

摘要:

我们证明光纤版本的经典定理的霍普夫和Leray-Samelson。我们的结果暗示了一类纤维H空间有理化后的纤维H平凡性。它们特别适用于泛伴随丛。由此,我们可以得到Crabb和Sutherland的一个结果[Proc. London Math. Soc.(2000),747-768],该结果在那里被用作建立他们的主要有限性结果的关键步骤。

英文摘要:

We prove fibrewise versions of classical theorems of Hopf and Leray-Samelson. Our results imply the fibrewise H-triviality after rationalization of a certain class of fibrewise H-spaces. They apply, in particular, to universal adjoint bundles. From this, we may retrieve a result of Crabb and Sutherland [Proc. London Math. Soc. (2000), 747-768], which is used there as a crucial step in establishing their main finiteness result.
