本文证明了具有给定底行(k1,...,kn)∈Zn,k1<k2<kn的单调三角形的个数由一个简单的乘积公式给出,该公式中显著地包含了(移位)算子.底行为(1,2,.,n)的单调三角形与n×n交错符号矩阵构成双射。
We show that the number of monotone triangles with prescribed bottom row (k1,…,kn)∈Zn, k1<k2<⋯<kn, is given by a simple product formula which remarkably involves (shift) operators. Monotone triangles with bottom row (1,2,…,n) are in bijection with n×n alternating sign matrices.
