摘要

摘要研究了具有(强非幂零)复结构的实维8非同构幂零李代数群，它们具有>[0，∞]的单参数族。通过限制a取有理值，我们得到了具有复杂结构的8维零流形存在无穷多个实同伦类型。此外，还构造了这种零流形上的平衡厄米度量和广义高杜川度量。

A Family of Complex Nilmanifolds with in finitely Many Real Homotopy Types

Abstract We find a one-parameter family of non-isomorphic nilpotent Lie algebras ga, with a > [0,∞), of real dimension eight with (strongly non-nilpotent) complex structures. By restricting a to take rational values, we arrive at the existence of infinitely many real homotopy types of 8-dimensional nilmanifolds admitting a complex structure. Moreover, balanced Hermitian metrics and generalized Gauduchon metrics on such nilmanifolds are constructed.
