论文摘要
我们提出了一种针对面向纤维三角形球形纤维束的Euler类的局部组合公式的基本方法。该方法基于节平均技术和简单(CO)同源性理论的非常基本知识。我们的公式是N.Mnëv的近亲。
We present an elementary approach to local combinatorial formulae for the Euler class of a fiber-oriented triangulated spherical fiber bundle. The approach is based on sections averaging technique and very basic knowledge of simplicial (co)homology theory. Our formulae are close relatives of those by N. Mnëv.
