Varieties of chain complexes and mixed dimer covers
Portia X. Anderson, Esther Banaian, Melanie J. Ferreri +3
A quiver representation consists of a collection of vector spaces along with a set of arrows, which are linear maps between these spaces. In this work, we study quiver representati…
Circular sorting in the alternating group
Melanie Ferreri, Eric Swartz, Nicholas J. Werner
The symmetric group is generated by transpositions, and problems of sorting permutations using transpositions are well studied. In recent work, Adin, Alon, and Roichman studi…
Enumerating Vector Parking Functions and their Outcomes Based on Specified Lucky Cars
Melanie Ferreri, Pamela E. Harris, Lucy Martinez +1
In a parking function, a car is considered lucky if it is able to park in its preferred spot. Extending work of Harris and Martinez, we enumerate outcomes of parking functions with…
Bijections for generalized Wilf equivalences
Melanie Ferreri
Starting with an inclusion-exclusion proof of a combinatorial identity, a direct bijection can be produced using recursive subtraction (sometimes with a direct combinatorial descri…
