Two-vertex generators of Jacobians of graphs

David Brandfonbrener, Pat Devlin, Netanel Friedenberg +4

We give necessary and sufficient conditions under which the Jacobian of a graph is generated by a divisor that is the difference of two vertices. This answers a question posed by B…

Perfect fractional matchings in k-out hypergraphs

Pat Devlin, Jeff Kahn

Extending the notion of (random) -out graphs, we consider when the -out hypergraph is likely to have a perfect fractional matching. In particular, we show that for each t…

A stability result using the matrix norm to bound the permanent

Ross Berkowitz, Pat Devlin

We prove a stability version of a general result that bounds the permanent of a matrix in terms of its operator norm. More specifically, suppose is an matrix over…

On "stability" in the Erdős-Ko-Rado theorem

Pat Devlin, Jeff Kahn

Denote by the random subgraph of the usual Kneser graph in which edges appear independently, each with probability . Answering a question of Bollobás, Naraya…

Some integer formula-encodings and related algorithms

Edinah K. Gnang, Patrick Devlin

We investigate the special class of formulas made up of arbitrary but finite com- binations of addition, multiplication, and exponentiation gates. The inputs to these formulas are…

Sets with High Volume and Low Perimeter

Patrick Devlin

In this paper, we consider a certain variation of the "isoperimetric problem" adopted for subsets of nonnegative integers. More specifically, we explore the sequence P(n) as descri…
