Angel–Gorin–Holroyd–Romik–Virág conjecture on random reduced words
Angel–Gorin–Holroyd–Romik–Virág conjecture on random reduced words
Let be the longest permutation, let be its inversion number, and choose a reduced word uniformly at random. Form the initial product and consider the locations of the 's in its permutation matrix. Random reduced-word limit-shape conjecture. As tends to infinity, the probability distribution of these 's approaches the surface measure of the sphere projected to two dimensions. The conjecture is stated as still open in the source.
