摘要

摘要:设N是一个单连通实数幂零李群，N是它的李代数，N是N上的一个格。如果N上的一个左不变复结构为Γ-rational，那么对于每一个s, HƏ′s,t(Γ/N)≃HƏ′s,t(nC);利用复化和标量限制，我们可以在一个幂零李群上构造不同的左不变复结构。研究了关联紧复零流形与霍奇数的关系。

Some relations between Hodge numbers and invariant complex structures on compact nilmanifolds

Abstract Let N be a simply connected real nilpotent Lie group, n its Lie algebra, and € a lattice in N. If a left-invariant complex structure on N is Γ-rational, then HƏ̄s,t(Γ/N) ≃ HƏ̄s,t(nC) for each s; t. We can construct different left-invariant complex structures on one nilpotent Lie group by using the complexification and the scalar restriction. We investigate relationships to Hodge numbers of associated compact complex nilmanifolds.
