Introductory Problem Solving Workshop
Presented by: Joyce Gong and Aaron Cushman
New to math competitions and problem solving? Join our free relaxed problem solving workshop based on AMC 8 and MATHCOUNTS material. Suitable for middle school students. Enjoy pizza after the end of the class.
If this problem set is too hard, then you are not ready yet.
If this problem set is too easy, then consider our other classes.
Location: Brownson Hall BR-180, Manhattanville University
Time: Tuesdays, 5-5:50 pm

Recreational Math Seminar
Our main event, open to all levels. Presenters and topics vary from week to week.
Location: Brownson Hall BR-180, Manhattanville University
Time: Tuesdays 6-7:30 pm
Sept 9
Title: Order in the Sort
Speaker: Matt Cushman, PhD
Abstract: Sorting a list of numbers is one of the most important families of algorithms. Similarly, the notion of "partially ordered set" is a fundamental concept used all over in
mathematics. We will discuss both of these concepts, give some examples, and discuss an elementary open question which has been open since the 1960s.
Sept 16
Title: Expander Graphs
Speaker: Dr. Brooke Feigon
Abstract: Is there a way to build the electricity grid in NYC that will both prevent occasional breaks in wires from causing mass blackouts, and also minimize the number of wires you’re using? We’ll explore this problem through “expander graphs” and see how these graphs are related to number theory and the Ramanujan conjecture.
Bio: Dr Feigon is a Professor of Mathematics at CUNY. She received her PhD in Mathematics from UCLA.
Sept 23
Title: On The Art Gallery Problem
Speaker: Dr. Ajay Deshpande
Abstract: How many guards are required to guard the interior of an art gallery with n walls? The Art Gallery Problem is a classic problem in computational geometry. A number of variations of this problem have been studied. I will begin by introducing the classic art gallery theorem that provides an upper bound on the number of vertex guards required. Then I will focus on a specific variation called the point-guard problem of finding the minimum number of points so that guards located at these points cover the interior of the art gallery and discuss approximate algorithms to solve this problem.
Bio: Ajay Deshpande received his PhD from MIT and currently works at Google. Previously he worked at IBM Research.
