Series: Research Horizons Seminar

This is a will be a panel made of two senior grad students, a post doc and a faculty member. The panelists will answer questions and give advice to younger graduate students on a range of topics including how to be a good citizen of the department and choosing an advisor.
The panelists are Dr. Kang, Dr. Kelly Bickel, Albert Bush, and Chris Pryby.

The standard map is a widely studied area-preserving system with application to many natural phenomena. When unperturbed, every orbit of this map lies on an invariant circle. In this talk we will explore what happens to these circles when the system is perturbed, employing both analytical and numerical tools. I will conclude by discussing some active areas of current research.

We'll look at some of the basics of potential theory in the complex plane. We'll also discuss how potential theory may be used in studying zeros of polynomials and approximation theory.

Have you heard the urban legend that an experienced college
recruiter can make an initial decision on whether or not to read your
resume in less than six seconds? Would you like to see if your current resume can survive the six-second glance?Would you like to improve your chances of surviving the initial cut? Do you know what happens to your resume once you hand it to the recruiter? How do you craft a resume that competes with 100,000 other resumes? Dr. Matthew Clark has supported college recruiting efforts for a
variety of large corporations and is a master at sorting resumes in six
seconds or under. Join us August 28th, 2013 in Skiles 005 at noon for a discussion of how most industry companies handle resumes,
what types of follow up activities are worth-while, and, how to improve
your chances of having your resume pass the "six second glance".

I will give an overview of how lattices in R^n are providing a powerful new mathematical foundation for cryptography. Lattices yield simple, fast, and highly parallel schemes that, unlike many of today's popular cryptosystems (like RSA and elliptic curves), even appear to remain secure against quantum computers. What's more, lattices were recently used to solve a cryptographic "holy grail" problem known as fully homomorphic encryption.
No background in lattices, cryptography, or quantum computers will be necessary for this talk -- but you will need to know how to add and multiply matrices.

A 1986 article with this title, written by M. Zuker and published by the AMS, outlined several major challenges in the area. Stating the folding problem is simple; given an RNA sequence, predict the set of (canonical, nested) base pairs found in the native structure. Yet, despite significant advances over the past 25 years, it remains largely unsolved. A fundamental problem identified by Zuker was, and still is, the "ill-conditioning" of discrete optimization solution approaches. We revisit some of the questions this raises, and present recent advances in considering multiple (sub)optimal structures, in incorporating auxiliary experimental data into the optimization, and in understanding alternative models of RNA folding.

In the last few years many problems of mathematical and physical interest, which may not be Hamiltonian or even dynamical, were solved using techniques from integrable systems. I will review some of these techniques and their connections to some open research problems.

I will discuss algebraic (sums of squares based) certificates for
nonnegativity of polynomials and their use in optimization. Then I will
discuss some recent results on degree bounds and state some open
questions.

I'll introduce the Hilbert transform in a natural way justifying it as a canonical operation. In fact, it is such a basic operation, that it arises naturally in a range of settings, with the important complication that the measure spaces need not be Lebesge, but rather a pair of potentially exotic measures. Does the Hilbert transform map L^2 of one measure into L^2 of the other? The full characterization has only just been found. I'll illustrate the difficulties with a charming example using uniform measure on the standard 1/3 Cantor set.
