Combinatorics and the Quadratic Formula
Abstract: We explore the connection between the quadratic formula and the Catalan numbers. We start with a piece of folklore, then move to examples including the drunk on the cliff. Then we discuss some combinatorial interpretations, the Riordan group, and involutions in the Riordan group.Time: Friday, February 23, 2018, 3:30-4:20 p.m.
