[分析] 不等式
給定一個real valued函數f定義在C^n上
1)f is a strictly convex function of (log|z_1|,...log|z_n|)
2)f is invarient under the torus action (S^1)^n
3)f has a critical point
4)f is proper
則可以找到兩個positive constants A, B > 0 s.t.
f(z_1 , ... , z_n) >= A log(|z_1|^2 + .... + |z_n|^2) - B
for all (z_1, ... , z_n) in (C-{0})^n.
希望各位能給一點提示或是相關資料可以參考^__^
