Abstract:We prove Fu's power series conjecture which relates the algebra of isometry invariant valuations on complex space forms to a formal power series from combinatorics which was introduced by Tutte. The $ n$th coefficient of this series is the number of triangulations of a triangle with $ 3n$ internal edges; or the number of intervals in Tamari's lattice $ Y_n$.

单位不变估值和Tutte序列

摘要:我们证明了傅的幂级数猜想,它把复杂空间形式的等距不变估值的代数与Tutte引入的组合数学的正规幂级数联系起来。该$ n $级数的th系数是具有$ 3n $内部边缘的三角形的三角剖分数量;或Tamari晶格中间隔的数量$ Y_n $
