### Pi Mu Epsilon Seminar – David Cruz-Uribe

302 Gordon Palmer Hall“The bread and butter of first semester calculus are optimization problems. In this talk we will start with a classic example: given a rectangular sheet of metal/paper/cardboard, cut equal size squares from each corner so that the sides can be folded up to make an open top box. Given the dimensions of the original rectangle,

302 Gordon Palmer HallBuilding Large Economic and Financial Networks “The study of high dimensional networks has increased dramatically. Group wise information from large datasets can be used to build networks where nodes represent variables and edges represent the conditional dependency between two variables. Economic policy makers can use these networks to measure impulse responses and determine how an

### Pi Mu Epsilon – Patricia Cahn (Smith College)

302 Gordon Palmer HallTitle: Stranger Strings Abstract: How can we describe all spaces of a given dimension? We'll start by describing 2-dimensional spaces, which look like donuts with any number of holes. Then we'll learn how to describe 3-dimensional spaces, by using knots to build portals in our familiar 3-dimensional space R^3.
