Independent Chains in Acyclic Posets

Nika Salia, Christoph Spiegel, Casey Tompkins +1

We consider the problem of determining the maximum order of an induced vertex-disjoint union of cliques in a graph. More specifically, given some family of graphs of…

Set systems related to a house allocation problem

Dániel Gerbner, Balázs Keszegh, Abhishek Methuku +4

We are given a set of buyers, a set of houses, and for each buyer a preference list, i.e., an ordering of the houses. A house allocation is an injective mapping from $A…

The Maximum Number of Paths of Length Three in a Planar Graph

Andrzej Grzesik, Ervin Győri, Addisu Paulos +3

Let denote the maximum number of copies of possible in an -vertex planar graph. The function has been determined when is a cycle of length or b…

The Maximum Number of Pentagons in a Planar Graph

Ervin Győri, Addisu Paulos, Nika Salia +2

In 1979, Hakimi and Schmeichel considered the problem of maximizing the number of cycles of a given length in an -vertex planar graph. They precisely determined the maximum numb…

Long path and cycle decompositions of even hypercubes

Maria Axenovich, David Offner, Casey Tompkins

We consider edge decompositions of the -dimensional hypercube into isomorphic copies of a given graph . While a number of results are known about decomposing into…

On forbidden poset problems in the linear lattice

Jimeng Xiao, Casey Tompkins

In this note, we determine the maximum size of a -free family in the lattice of vector subspaces of a finite vector space both in the non-induced case as well as…
