Pseudo-Polynomial Time Algorithm for Computing Moments of Polynomials in Free Semicircular Elements
arXiv:1901.08210
Abstract
We consider about calculating th moments of a given polynomial in free independent semicircular elements in free probability theory. By a naive approach, this calculation requires exponential time with respect to . We explicitly give an algorithm for calculating them in polynomial time by rearranging Schützenberger's algorithm.
