On the Number of Independent Sets in Uniform, Regular, Linear Hypergraphs

Emma Cohen, Will Perkins, Michail Sarantis +1

We study the problems of bounding the number weak and strong independent sets in -uniform, -regular, -vertex linear hypergraphs with no cross-edges. In the case of weak in…

The Widom-Rowlinson model, the hard-core model and the extremality of the complete graph

Emma Cohen, Péter Csikvári, Will Perkins +1

Let be the path on vertices with a loop at each vertex. D. Galvin conjectured, and E. Cohen, W. Perkins and P. Tetali proved that for any -regular simple g…

On the Widom-Rowlinson Occupancy Fraction in Regular Graphs

Emma Cohen, Will Perkins, Prasad Tetali

We consider the Widom-Rowlinson model of two types of interacting particles on d-regular graphs. We prove a tight upper bound on the occupancy fraction, the expected fraction of ve…

Lattice Path Matroids: Negative Correlation and Fast Mixing

Emma Cohen, Prasad Tetali, Damir Yeliussizov

Catalan numbers arise in many enumerative contexts as the counting sequence of combinatorial structures. In this work, we consider natural Markov chains on some of the realizations…

Inverse Expander Mixing for Hypergraphs

Emma Cohen, Dhruv Mubayi, Peter Ralli +1

We formulate and prove inverse mixing lemmas in the settings of simplicial complexes and k-uniform hypergraphs. In the hypergraph setting, we extend results of Bilu and Linial for…

Active Learning and Best-Response Dynamics

Maria-Florina Balcan, Chris Berlind, Avrim Blum +3

We examine an important setting for engineered systems in which low-power distributed sensors are each making highly noisy measurements of some unknown target function. A center wa…

The Dirt on Dry Mergers

Vandana Desai, Arjun Dey, Emma Cohen +2

Using data from the Spitzer Space Telescope, we analyze the mid-infrared (3-70 micron) spectral energy distributions of dry merger candidates in the Bootes field of the NOAO Deep W…
