一类纯G2流形的贝蒂数

Betti numbers of a class of barely G2 manifolds

Sergey Grigorian

摘要:

我们明确计算的贝蒂数的一类勉强G2流形-也就是说,G2流形实现为产品的卡-丘流形和一个圆,模的对合。我们考虑的特殊类是那些空间的卡-丘流形完全交叉的超曲面的产品复射影空间和对合是自由作用。

英文摘要:

We calculate explicitly the Betti numbers of a class of barely G2 manifolds - that is, G2 manifolds that are realised as a product of a Calabi-Yau manifold and a circle, modulo an involution. The particular class which we consider are those spaces where the Calabi-Yau manifolds are complete intersections of hypersurfaces in products of complex projective spaces and the involutions are free acting.
