Infinitely many finite simple groups of Lie type are not generated invariably by two elements of prime order

Robert M. Guralnick, John Shareshian, Russ Woodroofe

We show that there are infinitely many k for which Sp_{2k}(2) is not generated invariably by two elements of prime order.

Antichain cutsets in real-ranked lattices

Stephan Foldes, Russ Woodroofe

We show that in a rank supersolvable lattice that is graded by a bounded real interval, any antichain cutset is a level set for some appropriately constructed grading. As a consequ…

Strict Erdős-Ko-Rado theorems for simplicial complexes

Denys Bulavka, Russ Woodroofe

We show that if a simplicial complex is a near-cone of sufficiently high depth, then the only maximum families of small pairwise intersecting faces are those with a common intersec…

Princ-wiki-a Mathematica: Wikipedia editing and mathematics

David Eppstein, Joel Brewster Lewis, Russ Woodroofe +1

Over the past 20 years, Wikipedia has gone from a rather outlandish idea to a major reference work, with more than 60 million articles across all languages, including nearly 7 mill…

A short proof of the Hilton-Milner Theorem

Denys Bulavka, Russ Woodroofe

We give a short and relatively elementary proof of the Hilton-Milner Theorem.

A Hilton-Milner theorem for exterior algebras

Denys Bulavka, Francesca Gandini, Russ Woodroofe

Recent work of Scott and Wilmer and of Woodroofe extends the Erdős-Ko-Rado theorem from set systems to subspaces of k-forms in an exterior algebra. We prove an extension of the Hil…
