我们给出了一个多项式规模的代数分支程序,用于计算右量子矩阵的凯莱行列式。这是高效计算非交换行列式的罕见例子,也是量子群的首个此类例子。我们将结果扩展到q - 右量子矩阵的q - 凯莱行列式及其多参数推广。证明完全是组合性的,通过单词上的双射/对合关联凯莱、摩尔和瓦利安特行列式,然后利用Mahajan和Vinay著名的行列式构造得到结果。
英文摘要
We give an algebraic branching program of polynomial size which computes Cayley determinant of right quantum matrices. This is a rare example of an efficient computation of a noncommutative determinant, and the first such example for quantum groups. We extend the results to the $q$-Cayley determinant of $q$-right quantum matrices, as well as to their multiparameter generalization. The proofs are entirely combinatorial, as we relate Cayley, Moore and Valiant determinants using bijections/involutions on words. We then employ the celebrated determinant construction of Mahajan and Vinay (SODA'97), to obtain the results.
