On Cycles in Multiset Permutations, Parking Functions, and Related Structures
Calum Buchanan, Fabian Burghart, Stephan Wagner +1
In this paper we study cycles in multiset permutations and parking functions. As combinatorial objects, multiset permutations are essential building blocks for mappings and permuta…

Distribution of new statistics of parking functions and their generalizations
Stephan Wagner, Catherine H. Yan, Mei Yin
In this paper we present new results on the enumeration of parking functions and labeled forests. We introduce new statistics on parking functions, which are then extended to label…

Monomial identities in the Weyl algebra
Darij Grinberg, Tom Roby, Stephan Wagner +1
Motivated by a question and some enumerative conjectures of Richard Stanley, we explore the equivalence classes of words in the Weyl algebra, $\mathbf{k} \left< D,U \mid DU - UD =…
