摘要:

我们研究了可以通过组合拼接方法在$\mathbb{P}^n$中构造的实代数超曲面的拓扑结构,这些超曲面由双倍扩张的三角剖分构造。通过分析定义此类超曲面的多项式的实临界点,我们找到了各种Betti数之和的渐近上界。然后我们讨论了这些界限的精确性。

英文摘要:

We study the topology of the real algebraic hypersurfaces in $\mathbb{P}^n$ that can be constructed via combinatorial patchworking using triangulations that are dilations by two of other triangulations. By examining the real critical points of the polynomials that define such hypersurfaces, we find some asymptotical upper bounds on various sums of their Betti numbers. We then discuss the sharpness of those bounds.
