Rich Summer Internship participants Ryan Olsen and Abdullah Khan will be giving us 20 minute presentations on their work this summer!

Abdullah Khan

My work with Professor Medvedev involved studying specific parts of a Theorem by Hrushovski in a paper by Hirotaka Kikyo “On Generic Predicates and Automorphisms” in logic. My goal over the summer was to learn the necessary abstract algebra to parse this theorem and understand it. My final report consists of the preliminary mathematics needed to do this and an exposition of the theorem by Hrushovski from the perspective of an introductory student of mathematics.

Ryan Olsen

A theoretical cryptographic scheme based upon sending a string of bits, 0 and 1. This protocol circumvents the computational hardness assumptions found in most cryptosystems used today, although with a slight loss in accuracy. Its implementation and further improvements will be discussed.

There will be pizza and refreshments!

  • Welcome Back Party Fall 2019 Thursday 9/26/19 12:45pm - 1:45pm NAC 6/310

We will be meeting this day to discuss what kinds of events you might want to see the Math Club host, as well as various opportunities for undergraduate students like the department's new 4+1 joint Bachelor's/Master's degree program. Come grab some pizza and meet some other math enthusiasts!

  • 2019 Rich Summer Internship Math Presentations Tuesday 9/17/19 12:45pm - 1:45pm NAC 6/310

Rich Summer Internship participants Joe Winter and Samuel Young will be giving us 20 minute presentations on their work in two exciting fields.

Joe Winter

My work focuses on the dynamical system known as the perturbed doubling map, a function on the complex plane that maps a complex number z to z-squared + c, where c is a complex number known as the perturbation constant. My talk will detail computational approaches to estimating and visualizing the Julia set of this map. I will also discuss strategies used to estimate periodic points of the map which are then used to explore the relation between c and the maximization of a particular potential.

Samuel Young

Local Subgroup Structures of Abstract Commensurators The abstract commensurator of a group, Comm(G), generalizes the notion of the automorphism group Aut(G). We study a new variation of Comm(F_2), which embeds in Comm(F_2), which we show is not locally residually finite.

There will be pizza and refreshments!

  • Special Mathematics Colloquium: Prof. Linda Keen (Lehman College), Thursday 05/09/19 12:30pm - 1:30pm, NAC 6/114

This is a joint even with the CCNY AWM Chapter. Participants are invited to join the tea at noon in the Math Lounge (8th floor), and lunch immediately following the talk. We will show how the basic question of how to lay tiles in a room leads mathematicians to interesting questions and new concepts in geometry.

  • Grad Panel 2019 Tai-Danae Bradley, Jozef Dodziuk, Anna Tao, Friday 5/3/19 12:30pm - 2:00pm MR 702

On May 3rd we will be inviting Tai-Danae Bradley and Jozef Dodziuk from the Grad Center, and Anna Tao from CCNY as panelists on the Friday, May 3 Graduate Panel.

The math club and AWM, alongside with Dr. Alice Medvedev, will be hosting an REU Awareness Event. She will be talking about the kinds of REUs available this summer, where to apply, and how to strengthen your application. REUs typically admit first semester sophomores to first semester seniors and range in difficulty.

  • Division of Science Research Opportunities Fair Tuesday 11/20/18 12:15pm Marshak Cafe

The Division of Science will be hosting a [Research Opportunities Fair] in the Marshak cafe. The Math Club and other organizations will be tabling there from 12:15 and on. So feel free to come by!

  • Maximal Volume Entropy Rigidity of RCD(-(N-1),N) Presenters, Thursday 10/11/18 12:30-2:00 NAC 6/114

For n-dimensional Riemannian manifolds M with Ricci curvature bounded below by -(n-1), the volume entropy is bounded above by (n-1). If M is compact, it is known that the equality holds if and only if M is hyperbolic. We show the same maximal entropy rigidity result holds for a class of metric measure spaces known as RCD(K,N) spaces. While the upper bound follows quickly, the rigidity case is quite involved due to the lack of a smooth structure on these spaces.

  • Seven Bridges of Konnigsberg Jason Redman, Thursday 10/4/18 12:45pm - 2:00pm NAC 4/108

In 1736, Euler was given a problem to which he said there is no solution. This problem laid the foundations of graph theory and prefigured the idea of topology. We will talk about this problem and why it was so significant along with some fun explorations into the world of graph theory!

  • Undergraduate Lecture Series:

The Math Department organized a student seminar designed to have faculty present accessible lectures to start conversations on advanced mathematics. Those talks were accessible to undergraduate students and covered a wide range of topics. For more information, please check out the seminar website.
