Some Known Results of the Stable Solution in J-flow
Chao-Ming Lin (University of California, Irvine)

Abstract:

The J-flow was introduced by Donaldson [1] from the point of view of moment maps, as well as Chen [2] in his study of the Mabuchi energy. In [3], Song and Weinkov showed that the stable solution of the J-flow is equivalent to a positivity condition. Unfortunately, it is hard to check this condition, thus in [4], Lejmi and Szekelyhidi proposed a numerical positive condition, which is conjectured to be equivalent to the stable solution. In this talk, I will try to show the existence of stable solution in some simple cases and try to give some insights into a constraint which is related to Donaldson-Futaki type invariant.
