Chapter six discusses the connection about the hypoelliptic form with the first Betti number of manifold.
第六章讨论了亚椭圆微分形式与流形的第一Betti数之间的关系。
In the present paper, we obtain some remarks on holomorphic vector bundles on some non-algebraic compact complex surfaces with odd first Betti number. In particular, we get a description of IS2 ( X, 0) of exceptional Hopf surface here.
本文得到一些有关一类第一Betti数为奇数的曲面上的全纯向量丛的结果，以及例外Hopf曲面上的集合IS2（X，0）的描述。
This paper establishes an upper bound on the Betti deficiency ξ( G) in terms of the dominate number as well as the the girth of G, and thus gives a lower bound on the maximum genus.
本文利用G的支配数和围长给出了G的Betti亏数ξ（G）的一个上界，从而也给出了最大亏格γM（G）的一个下界，而且它是可达的；
