Upcoming Events:

Past Events:

  • REU Awareness Seminar Fall 2019 Tuesday 11/12/19 12:45-1:45 NAC 6/310

Alice Medvedev and a few undergraduate students will be speaking about REUs (Research Experiences for Undegraduates), and why they matter. They will offer advice about improving your chances of being accepted into an REU, and share their personal experiences with you all.

  • An Introduction to Group Theory Thursday 11/14/19 12:45-1:45 NAC 6/310

This is an interactive event headed by Jason Redman aimed at math and physics students to introduce the concept of groups and group homomorphisms. We will look at concrete examples of symmetry groups, study group structures through Cayley diagrams, and construct isomorphisms through them.

  • SAGE Programming Workshop: Representation Theory of Groups and Algebras Thursday 11/21/19 12:45-2:15 NAC 1/511A (Artino Lab)

Pavel Javornik will be running a programming workshop in the Artino computer labs in SAGE, an open-source alternative to Mathematica that can be run on a browser. We will introduce the ideas behind representations, motivate the left-regular representation as a tool in the study of modules over group algebras, and use SAGE to bring some of that to life. For those interested in getting a head start, the first few sections of this paper might provide some insight.

  • 2019 Rich Summer Internship Math Presentations II Tuesday 10/10/19 12:45-1:45 NAC 6/310

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 12:45-1:45 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 12:45-1:45 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(F2), which embeds in Comm(F2), 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 12:30-1:30, 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 12:30-2:00 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. We will be asking them questions about the most important things you need to know for getting into a graduate program, and then open the floor for any questions you might have.

  • Data Science Panel 2019 , Roland Maio, Grant Long, Diana Saafi, Thursday 3/13/19 5:30-7:00 NAC 1/203

The AWM, Math Club, and Women in Computer Science are hosting a data science panel, where we will have professionals and academics at various levels talking about what it is like to be a data scientist. We invite everyone to come listen and ask questions.

  • REU Info Session Alice Medvedev, Thursday 1/31/19 4:00-5:00 NAC 1/511E

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 12:15 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!

  • Rich Summer Intern Presentations Tuesday 11/13/18 12:30-1:50 NAC 7/312

We will be having some students presenting the work they did over the summer with the Math department in NAC 7/312 from 12:30 to 1:50. So if anyone wants to come hang out and discuss about the type of research undergraduates get into, feel free to come by. We'll also have food and refreshments.

  • Becoming a Math Major Michael Shub, Bianca Santoro, Khalid Bourabee, Christian Wolf, Thursday 11/1/18 12:30-1:50 NAC 6/114

We will be hosting an event in NAC 6/114, 12:30 - 1:50. We will have the chair, Michael Shub, professors Bourabee, Wolf, and Santoro talking about things they find interesting and what to expect in higher level math courses, as well as what you might do with a math degree. There will be free food, and everyone is welcome to attend!

  • 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 12:45-2:00 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!

We're currently putting together a list of all the events we've created, or been a part of. If you're interested, check back later!
