Futaki invariant and cm polarization
WebBando-Futaki invariant is the same as the Futaki invariant given as r1(x) = -(n+i-dr-^n+1){d-1K. n Our method can be applied, in principle, to the case of complete intersections and toric varieties. However, the computation is complicated using the current notation. Therefore our goal is to create an abstract setting from our current ideas WebJun 1, 2016 · Futaki Invariant and CM Polarization Authors: Gang Tian Sichuan Agricultural University Request full-text Abstract This is an expository paper.
