摘要：
The braid group on n-strands of a tree T, denoted BnT, has free abelian integral homology groups in every dimension. The rank of H-i (BnT) is equal to the number of i-cells in (UCT)-T-n, the unlabelled configuration space of n points on T, which are critical with respect to a certain discrete Morse function.
