Firstly, we discuss the singular topological structure of the Gauss - Bonnet - Chern theorem based on the Chern - Weil theory.
首先, 从Chern-Weil理论出发研究了Gauss -Bonnent-Chern 定理的奇异性拓扑结构.
Using the witten index for a supersymmetric field theory, we proved the Gauss - Bonnet - Chern theorem.
利用超对称理论的Wittenindex, 我们证明Gauss -Bonnet-Chern 定理.
Chern was the author of a famous theorem combining topology and geometry.
