Parking Cascades: From the Simplest Sequence to Motzkin and Catalan
Ben Adenbaum, Néstor F. Díaz Morera, Jennifer Elder +3
We introduce -cascading parking functions, a parametrized variant of parking functions in which cars form bumping cascades of up to cars. Setting recovers cla…
Inversions in parking functions
Kyle Celano, Jennifer Elder, Kimberly P. Hadaway +3
In this paper, we obtain a q-exponential generating function for inversions on parking functions via symmetric function theory and also through a direct bijection to rooted labeled…
Statistics on -interval parking functions
Kyle Celano, Jennifer Elder, Kimberly P. Hadaway +4
The displacement of a car with respect to a parking function is the number of spots it must drive past its preferred spot in order to park. An -interval parking function is o…
Enumerating Flat Fubini Rankings
Kenny Barrese, Jennifer Elder, Pamela E. Harris +1
Recall that the set of Fubini rankings on competitors consists of the -tuples that encode the possible rankings of competitors in a competition allowing ties. Moreover,…
A Probabilistic Parking Process and Labeled IDLA
Pamela E. Harris, Thiago Holleben, J. Carlos Martínez Mori +3
In 1966, Konheim and Weiss [33] introduced a now classical parking protocol. The deterministic process and its resultant objects, known as parking functions, have since become a fa…
The support of Kostant's weight multiplicity formula is an order ideal in the weak Bruhat order
Portia X. Anderson, Esther Banaian, Melanie J. Ferreri +7
For integral weights and of a classical simple Lie algebra , Kostant's weight multiplicity formula gives the multiplicity of the weight in the irreducible…
Boolean intervals in the weak Bruhat order of a finite Coxeter group
Ben Adenbaum, Jennifer Elder, Pamela E. Harris +1
Given a Coxeter group with Coxeter system , where is finite. We provide a complete characterization of Boolean intervals in the weak order of uniformly for all C…
On the Lucky and Displacement Statistics of Stirling Permutations
Laura Colmenarejo, Aleyah Dawkins, Jennifer Elder +5
Stirling permutations are parking functions, and we investigate two parking function statistics in the context of these objects: lucky cars and displacement. Among our results, we…
Vacillating parking functions
Bruce Fang, Pamela E. Harris, Brian M. Kamau +1
For any integers , we introduce a new family of parking functions called -vacillating parking functions of length . The parking rule for -vacillating parkin…
Unit interval parking functions and the -Fubini numbers
S. Alex Bradt, Jennifer Elder, Pamela E. Harris +5
We recall that unit interval parking functions of length are a subset of parking functions in which every car parks in its preference or in the spot after its preference, and F…
On some discrete statistics of parking functions
Ari Cruz, Pamela E. Harris, Kimberly J. Harry +5
Recall that is a parking function if its nondecreasing rearrangement satisfies for all . In thi…
Interval and -interval Rational Parking Functions
Tomás Aguilar-Fraga, Jennifer Elder, Rebecca E. Garcia +12
Interval parking functions are a generalization of parking functions in which cars have an interval preference for their parking. We generalize this definition to parking functions…
Cost-sharing in Parking Games
Jennifer Elder, Pamela E. Harris, Jan Kretschmann +1
In this paper, we study the total displacement statistic of parking functions from the perspective of cooperative game theory. We introduce parking games, which are coalitional cos…
