Speaker: Lou Shapiro, Howard University
Date and time: Tuesday, January 30, 1-2pm
Place: Rome 771
Title: 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 combinatorial interpretations, the Riordan group, and involutions in the Riordan group.
