Princeton University Press gave us a bunch of new books! They’re on the shelf in Fine Hall Common Room. Feel free to check them out! Please keep them in the Common Room though!
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!http://en.wikipedia.org/wiki/Yakov_Sinai
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.
When: 5:00 pm – 6:00 pm, April 9th (coming Wednesday)
Where: Fine 214
Who: Prof. Adam Levine, who specializes in low-dimensional topology (and he only joined Princeton this academic year!) You can check out some details here:https://www.math.princeton.edu/news/home-page/mathematics-department-welcomes-new-faculty
Title: Knot Concordance
Abstract: Concordance is the study of which knots in three-dimensional space can be realized as the boundaries of embedded disks in four dimensions, a question that was first introduced by Princeton’s Ralph Fox and John Milnor in the 1950s. This question is closely tied to many of the strange features of four-dimensional topology and is the subject of much current research. I’ll provide an overview of this subject and an introduction to some of the modern tools that have led to breakthroughs in our understanding.
Check out the slides of yesterday’s awesome colloquium on “Cool theorems proved by undergraduates” by Prof. Ken Ono from Emory University! :D
Abstract. I will explain some cool theorems in number theory that undergraduates
have proven in the last few years. This will include work on the distribution of
primes, number fields, and extensions if works by Euler-Jacobi-Nekrasov-Okounkov-Serre. Let me explain.
Come Meet Professor Dunham, visiting professor and author of Journey Through Genius, this Thursday at 6 in the Butler Private Dining Room!
Sign up for “Meet Your Professor Dinner” here: https://wass.princeton.edu/pages/viewcalendar.page.php?makeapp=1&cal_id=1720
William Dunham is visiting Princeton this semester and teaching a Freshman Seminar titled “The Great Theorems of Mathematics.” He is a historian of mathematics who has spoken at scores of institutions — e.g., Harvard, Penn, Swarthmore — and written multiple books on the subject — e.g., Journey Through Genius(1990), Euler: The Master of Us All (1999), and The Calculus Gallery (2005). Except for the weather, he’s very much enjoying his term at Princeton, where he’s addressed the Mathematics Colloquium and given the 2014 Pi Day talk to the Math Club. And he’s thrilled to be part of this “Meet Your Professor” dinner.
