The Cycle Descent Statistic on Permutations Jun Ma Shi-Mei Ma Yeong-Nan Yeh Xu Zhu DOI: https://doi.org/10.37236/5673 Keywords: Permutations, Cycle descents, Perfect matchings, Involutions, Eulerian polynomials Abstract In this paper we study the cycle descent statistic on permutations. Several involutions on permutations and derangements are constructed. Moreover, we construct a bijection between negative cycle descent permutations and Callan perfect matchings.
