Title: Increasing and Invariant Parking Sequences 

Abstract: The notion of parking sequences is a new generalization of parking functions introduced by Ehrenborg and Happ. In the parking process defining the classical parking functions, instead of each car only taking one parking space, the cars are allowed to have different sizes and each takes up a number of adjacent parking spaces after a trailer that was parked at the start of the street. A preference sequence in which all the cars are able to park is called a parking sequence. In this talk, we will look at increasing parking sequences and their connections to lattice paths. We will also discuss two notions of invariance in parking sequences and present various characterizations and enumerative results. This is joint work with Catherine Yan.
