Combinatorics of the 2-species exclusion processes, marked Laguerre histories, and partially signed permutations (2005.05895v1)
Published 12 May 2020 in math.CO
Abstract: Starting from the two-species partially asymmetric simple exclusion process, we study a subclass of signed permutations, the partially signed permutations, using the combinatorics of Laguerre histories. From this physical and bijective point of view, we obtain a natural descent statistic on partially signed permutations; as well as partially signed permutations patterns.
