First colloquium of the semester!

We are having our first math department colloquium on Thursday, February 16 on the Szemerédi-Trotter theorem, which is a really cool theorem in combinatorial geometry that gives an upper bound on the number of incidences between lines and points in the plane.
Who: Professor Zeev Dvir
What: The Szemerédi–Trotter theorem
When: Thursday at 4:30
Where: Fine 110
Food: Yes (Pizza from Princeton Pi)

PUMaC 2016!

The 11th annual Princeton University Mathematics Competition is barely a month away! As one of the largest math competitions for high school students in the world, we attract hundreds of students to Princeton to engage in a day-long adventure in mathematics. The main website for the event is here.

As a student-run event, we are always looking for volunteers to help out!

Date: November 19th (Saturday)

Time: 9 am – noon, but we would also appreciate extra volunteers for the afternoon

Role: Proctoring

Perks: FREE (yummy) breakfast, FREE (catered) lunch, FREE (sexy) t-shirt

If you are interested in helping out, you can contact Additionally, if you are interested in helping test-solve, you can contact

First Colloquium of the Year!

You may have heard of Hamlet by William Shakespeare. BUT have you heard of Ham-set by Jerry Shakespeare? Jerry Shakespeare, who looks resounding similar to his brother and also apparently had very similar dialogue in his stories, is a newly discovered gem. Come discover the newly uncovered, six-hundred year old manuscript in its truest form this Tuesday!

Who: Prof. Jerry Wang

What: To Square or Not to Square

When: 5:00 PM — 6:00 PM, Tuesday, 10/18

Where: Fine 110

Abstract: I will be speaking about my two research areas on rational points on hyperelliptic curves and squarefree sieve of discriminants.

First Board Game Night of the Year!

Welcome back to campus! Hope everyone had a great summer.

Grad school info session, Friday, May 9

What: info session on applying to graduate schools.
Where: Fine common room
When: Friday 5/9, 3:30pm (a.k.a. tea time!)
Seniors: If you can make it, please let me know! We will are mainly be sharing our experiences with the application process.
Non-seniors: If you’re interested at all in applying to graduate school, you should come and learn from our experiences. Bring questions!


Undergraduate Colloquium, Wednesday, May 7th

We will be having a colloquium this coming Wednesday at 5 pm in Fine 214. The speaker will be Prof. Gang Tian who specializes in geometric analysis. Check out his profile/wikipedia page here:
The title of the talk will be “Conic spherical metrics”. Here is the abstract:
 I will discuss the problem of constructing spherical structures on 2-sphere with prescribed conic angles and its connection to geometric stability. In the end, I will briefly discuss higher dimensional analogue of this problem.
Hope to see you there!

Undergraduate Colloquium, Monday, April 28

The next colloquium will be this coming Monday, 4/28, given by Prof. Yakov Sinai. It will be at 5pm in Fine 322. He will be talking about deterministic chaos and here is the abstract:

Deterministic chaos is a property of deterministic dynamics. I shall explain main properties of chaotic dynamics and give some example of chaotic dynamical systems.

Prof. Sinai is known for his work in dynamic systems. As many of you may have heard, he received the Abel Prize, which is often described as the mathematician’s Nobel Prize, not long ago. Check out his wikipedia page if you are interested!

Undergraduate Colloquium, Wednesday April 23

When: 4:30 pm – 5:30 pm, April 23
Where: Fine 214
Who: Prof. Schapire, who is a professor in the department of Computer Science and specializes in theoretical and applied machine learning.
Title: How to Play Repeated Games

This talk will describe a simple, general algorithm for learning to play any matrix game against an unknown adversary.  The algorithm can be shown never to perform much worse than the best fixed strategy, even if selected in hindsight.  Moreover, because of the algorithm's moderate resource requirements, it can be used even when working with extremely large game matrices.  Taken together, these properties make the algorithm a good fit for a range of machine-learning applications, some of which will be discussed, for instance, to the problem of learning to imitate the behavior of an "expert" while attempting simultaneously to improve on the expert's performance.
