In this paper, we firstly give the distribution of the major index over generalized Schr\\\"{o}der paths. Then by providing a bijection between generalized Schr\\\"{o}der paths and row-increasing tableaux of skew shapes with two rows, we obtain the distribution of the major index and the amajor index over these tableaux. We also generalize a result of Pechenik, and give the distribution of the major index over increasing tableaux of skew shapes with two rows. Especially, a bijection from row-increasing tableaux with shape $(n,m)$ and maximal value $n+m-k$ to standard Young tableaux with a skew shape is obtained.", "revisions": [ { "version": "v1", "updated": "2020-02-05T15:53:08.000Z" } ], "analyses": { "subjects": [ "05A15", "05E05" ], "keywords": [ "skew shape", "generalized schröder paths", "standard young tableaux", "distribution", "row-increasing tableaux" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable" } } }
