摘要翻译：
我们将I.Coanda和G.Trautmann(2006)证明的射影空间上向量丛的巴比伦塔定理的变体推广到射影空间上主$G$-丛的情形，其中$G$是定义在代数闭域上的线性代数群。在证明过程中，我们对这类主g$-束的结构有了一些新的认识。

英文摘要：
  We generalise the variant of the Babylonian tower theorem for vector bundles on projective spaces proved by I. Coanda and G. Trautmann (2006) to the case of principal $G$-bundles over projective spaces, where $G$ is a linear algebraic group defined over an algebraically closed field. In course of the proofs some new insight into the structure of such principal $G$-bundles is obtained.
