Speaker: Lou Shapiro, Howard University
Date and time: Tuesday, January 30, 1–2pm
Place: Rome 771

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.
