# Association for Women in Mathematics (AWM)

We are the CCNY student chapter of the **Association for Women
in Mathematics (AWM)**. We want to help foster a sense of
community among math enthusiasts at CCNY. We organize various
events with the Math Club including group meetings, invited
speakers, and community outreach. Our goal is to have students and
faculty interact outside of the classroom and to form a support
system for each other.

### Club room

The current location of AWM (and also math club) is Marshak 308A.

### Student seminar:

In Fall 2023, the student seminar will meet either Tuesday or Thursday 12:30PM - 1:30 PM every week that we aren't running another event. Titles and abstracts of upcoming and past talks can be found below. Everyone is welcome to attend--all the talks should be accessible to upper-level undergraduates and beginning graduate students. Snacks and drinks will be provided. If you're interested in giving a talk, email ekimbro000@citymail.cuny.edu.

### How to join:

All CCNY students are welcome to join. All members receive complimentary membership in the AWM. Events and resources are announced in several locations.

### Upcoming Events

**Welcome Back Party**(Thursday September 7th 2023, 12:30-2:00, Marshak 308A)Come say hi to your returning friends and meet new students! There'll be (free) snacks and drinks.

**Student Seminar: Phase transitions and one-sided shift spaces, by Elliot Kimbrough-Perry**(Tuesday September 12th 2023, 12:30-1:30, Marshak 308A)A phase transition is a sudden change in the equilibrium of a dynamical system. I will introduce the definition of a phase transition, a shift space, and some related notions such as topological entropy, then sketch the construction of a potential on a one-sided shift that exhibits one phase transition.

**Student Seminar: Computability of equilibrium measures, by Emma Dinowitz**(Tuesday September 19th 2023, 12:30-1:30, Marshak 308A)**Student Seminar: Higher order Jacobian matrices, by Tabitha Ramirez**(Tuesday September 26th 2023, 12:30-1:30, Marshak 308A)**Student Seminar: Graph C* algebras, by Adrian Cabreja**(Tuesday September 26th 2023, 12:30-1:30, Marshak 308A)**Mathematical Art Day**(Tuesday October 3rd 2023, 12:30-2:00, Marshak 308A)**Halloween Party**(Tuesday October 31st 2023, 12:30-2:00, Marshak 308A)

### Past Events

**Math Department End of Semester Party**(Tuesday May 16th 2023, 12:00-2:00, NAC 8/133)t's time for the math department end of semester party! Come celebrate all the hard work you've done this year and send off the students who are graduating! There will be food, drinks, music, and we're hoping to get a good turnout of both faculty and students!

**AWM Talk: The BHK Interpretation of Proof and the Curry-Howard Correspondence. by Sevan Bharathan**(Thursday May 11th 2023, 12:30-1:30, Marshak 308A)The Brouwer-Heyting-Kolmogorov interpretation of proof, initially ideated by L.E.J. Brouwer in the early 1900s and later formalized independently by both Arend Heyting and Andrey Kolmogorov, suggests that a proof of a theorem is a construction of a certain mathematical object. This revelation, when seen through the lens of computer science, tells a different story: that a proof is a typed computer program, and that the resultant theorem is the type of its output, i.e., the Curry-Howard Correspondence. I will provide a history and statement of the correspondence and prove that intuitionistic natural deduction is in correspondence with lambda calculus. I will also discuss some more recent generalizations of this idea, namely Homotopy Type Theory and categorical semantics in general.

**AWM Talk: The Prime Number Theorem and Chebyshev’s Functions by William Taylor**(Thursday May 4th 2023, 12:30-1:30, Marshak 308A)A key step on the way to the proof of the Prime Number Theorem was Chebyshev’s introduction of arithmetic functions on the primes and their powers that compensate for their decreasing densities, and which should therefore grow approximately linearly. Proving this fact is equivalent to the PNT, but related statements bounding the growth of these functions can be obtained without complex analysis. This talk will explore these functions and hint at the remaining steps needed to prove the PNT.

**AWM Talk: Cohomology and shifts of finite type by Elliot Kimbrough-Perry**(Thursday April 27th 2023, 12:30-1:30, Marshak 308A)A (finite) shift space is a type of measure theoretical dynamical system in which the underlying set is the countable product of a finite set, called an alphabet, with itself. Such a space is typically equipped with a measure (typically either a Bernoulli or Markov measure), and the shift map. In 2003, P. Walters produced a necessary and sufficient condition for a continuous function on a two-sided shift to be cohomologous to a continuous function on a one-sided shift. I will introduce this result as well as some related results, and, if time permits, discuss applications to subshifts.

**AWM Talk: Factoring the Dedekind-Frobenius Determinant by Gabriela Brown**(Thursday April 20th 2023, 12:30-1:30, Marshak 308A)In the early 1900s Dedekind asked Frobenius a question about groups that lead to the creation of character theory, and began the field we now know as representation theory. The question he posed was this: consider the multiplication table of a group as a symbolic matrix. If you take the determinant symbolically, can you factor it? This talk will summarize the work of Frobenius on this classical question, and if time permits consider how the approach changes if the question is instead asked about a semigroup, an algebraic object with much less structure.

**AWM Talk: Martingales and Abracadabra, by Julio Diaz**(Thursday Mar 30th 2023, 12:30-1:30, Marshak 308A)Martingales are the mathematical abstraction of a fair game that have numerous applications in probability theory. The name originates from a class of betting strategies from 18th century France. In this talk, we will introduce martingales and Doob’s optional stopping theorem, and then use these tools to calculate the expected time for a monkey to type the word ABRACADABRA. If time permits we will also use martingales to prove Cayley’s formula for the number of spanning trees of a complete graph.

**Pi Day Party**(Tuesday Mar 14th 2023, 12-2, Marshak 308A)Friends! It's once again that time of year when we gather to celebrate pi. (And also our favorite pies: apple pie, pizza pie, pie charts). There will be food, drinks, music, and games (including another round of our integral competition). Be there or be square!

**AWM Talk: What are Thompson's Groups? by Adrian Cabreja**(Thursday March 8th 2023, 12:30-1:30, Marshak 308A)Thompson’s group F was first defined in 1965 by Richard Thompson. It has since been studied in the context of algebraic topology, category theory, computer science, shape theory and other mathematical fields. The group itself is very interesting since it has properties that appear to be paradoxical. For example 1. F contains the direct sum of infinitely many copies of itself, yet it is finitely presented. 2. F has exponential growth but contains no free groups of rank 2. The purpose of this talk is to define Thompson’s group F in both its analytic and geometric interpretation, while also presenting some of its interesting properties.

**Resume Workshop**(Thursday Feb 9th 2023, 12:30-1:30, Marshak 308A)Are you applying for jobs, internships, or grad school? This Thursday from 12:30-1:30 we're running a resume workshop! If you've never made one before, we'll have templates for whatever kind of resume/CV you need. And if you do have a resume, bring it in and we'll give you feedback on how to highlight your skills and experience. This event will also be a Zoom event, so join us in person in MR 308A, or on video for members on our mailing list.

**ENYGMMa seminar supporting gender minorities in mathematics**(Friday Feb 10th 2023, 12:30-4:15, at the CUNY Graduate Center)This seminar is joint-organized by several NY universities, and will have a catered lunch, talk by Prof. Moira Chas (Stonybrook), and a panel on careers in Math. The event is happening at the CUNY Graduate Center on Friday, February 10 2023 from 12:30-4:15. RSVP here!

**Welcome back coffee and tea!**(Thursday Jan 26th, 12:30-1:30, Club Room)Welcome back everyone! We'll be having coffee/tea and donuts during club hours this week to kick off the beginning of the semester. Say hi to the friends you haven't seen all break, and welcome new classmates! See you Thursday 12:30-1:30 in Marshak 308A.
