### Computer Science/Discrete Mathematics Seminar II

Online List Labeling: Breaking the log$^2$ n Barrier
Nicole Wein
10:30am|Simonyi Hall 101 and Remote Access

The online list labeling problem is a basic primitive in data structures. The goal is to store a dynamically-changing set of n items in an array of m slots, while keeping the elements in sorted order. To do so, some items may need to be moved over...

### Special Year Research Seminar

Products of primes in arithmetic progressions
2:00pm|Simonyi 101 and Remote Access

A conjecture of Erdős states that for every large enough prime q, every reduced residue class modulo q is the product of two primes less than q. I will discuss my on-going work with Kaisa Matomäki establishing among other things a ternary variant of...

### Harmonic Analysis Afternoon

An Introduction to the Decoupling of Higher Dimensional, Zero Curvature Hypersurfaces
2:00pm|Simonyi 101 and Remote Access

The ruled hypersurfaces are distinguished by being comprised of lines. When this characteristic exists as a consequence of vanishing principal curvatures, it yields possibilities for comparison with cylinders extending over lower-dimensional...

### Harmonic Analysis Afternoon

A Fractal Uncertainty Principle for Discrete 2D Cantor Sets
Alex Cohen
3:15pm|Simonyi 101 and Remote Access

A fractal uncertainty principle (FUP) states that a function `f' and its Fourier transform cannot both be large on a fractal set. These were recently introduced by Semyon Dyatlov and collaborators in order to prove new results in quantum chaos. So...

### Analysis & Mathematical Physics

4:30pm|Simonyi 101 and Remote Access

I will talk about three interesting ingredients that goes into the results on H\"{o}rmander type operators I presented at Princeton (joint with Shaoming Guo and Hong Wang). They are all related to algebraic or geometric properties of multivariate...

### Mathematical Conversations

Bi-Lipschitz Equivalence to the Euclidean Space
6:00pm|Birch Garden, Simons Hall

In dimension two, Urs Lang and Mario Bonk proved that a surface, homeomorphic to the plane, is bi-Lipschitz to the Euclidean space if its total Gauss curvature is smaller than that of the hemisphere. In this talk, I will explain what is known in...
