$χ_y$ -亏格的路径积分推导
A path integral derivation of $χ_y$-genus
摘要:
复流形的Hirzebruch $χ_y$ -亏格的公式是Hirzebruch-Riemann-Roch公式的一个推论。Todd亏格、Euler数和Signature的经典指数公式分别对应于复变$y=$为0、-1和1的情况。本文基于超对称量子力学给出了这个公式的{ \it direct}推导。
英文摘要:
The formula for the Hirzebruch $χ_y$-genus of complex manifolds is a consequence of the Hirzebruch-Riemann-Roch formula. The classical index formulae for Todd genus, Euler number, and Signature correspond to the case when the complex variable $y=$ 0, -1, and 1 respectively. Here we give a {\it direct} derivation of this nice formula based on supersymmetric quantum mechanics.
