Ten Points on a Cubic

Will Traves, David Wehlau

The 16-year old Blaise Pascal found a way to determine if 6 points lie on a conic using a straightedge. Nearly 400 years later, we develop a method that uses a straightedge to chec…

Permutations Avoiding Certain Partially-ordered Patterns

Kai Ting Keshia Yap, David Wehlau, Imed Zaguia

A permutation $π$ contains a pattern $σ$ if and only if there is a subsequence in $π$ with its letters are in the same relative order as those in $σ$ . Partially ordered patterns (P…

Subregular $J$ -rings of Coxeter systems via quiver path algebras

Ivan Dimitrov, Charles Paquette, David Wehlau +1

We study the subregular $J$ -ring $J_{C}$ of a Coxeter system $(W, S)$ , a subring of Lusztig's $J$ -ring. We prove that $J_{C}$ is isomorphic to a quotient of the path algebra of the doub…
