Special Year Workshop on p-adic Arithmetic Geometry

Revisiting the Motivic Cohomology of Schemes
Matthew Morrow
10:00am|Wolfensohn Hall

Abstract: Since the original conjectures of Beilinson and Lichtenbaum in the 80s, several versions of motivic cohomology have been introduced and developed, notably by Voevodsky. Most classically, Bloch's higher Chow groups provide the accepted...

Variations on Fefferman's Ball Multiplier Theorem
2:30pm|Simonyi Hall 101 and Remote Access

What happens to an Lp function when one truncates its Fourier transform to a domain? This question is now rather well understood, thanks to famous results by Marcel Riesz and Charles Fefferman, and the answer depends on the domain: if it is a...

Special IAS/PU Symplectic Geometry Seminar

Invariant Sets in Three-Dimensional Energy Surfaces
Rohil Prasad
1:00pm|Simonyi 101 and Remote Access

Let $H$ be any smooth function on $R^4$ and let $Y$ be any compact and regular level set. I'll explain a proof that $Y$ admits an infinite family of proper compact subsets that are invariant under the Hamiltonian flow, which moreover have dense...

Strongly Invertible Knots, Khovanov Homotopy, and Localization
Robert Lipshitz
9:15am|Remote Access

Strong inversions are a class of order-2 symmetries of knots in . Building on work of Seidel-Smith, Lidman-Manolescu, Stoffregen-Zhang, and others, we will describe a relationship between the Khovanov homology of a knot with a strong inversion and...

Squarefree Numbers in Short Intervals
Mayank R. Pandey
4:30pm|Simonyi 101 and Remote Access

We count squarefree numbers in short intervals [X, X+H] for H > X^{1/5 - $\delta$}, where $\delta$ > 0 is some absolute constant. This improves on the exponent 1/5 shown by Filaseta and Trifonov in 1992. 

 

In improving bounds on the number of...

Mathematical Conversations

Propagation of Randomness Under Nonlinear Wave Equations
6:00pm|Birch Garden, Simons Hall

In recent years, there has been much work on nonlinear wave equations with random initial data. Most of this work has focused on the behavior of such nonlinear waves on small scales. In this talk, I will pose a problem concerning the behavior on...

Emmy Noether Lectures

Real Local Langlands as Geometric Langlands on the Twistor-P^1
Peter Scholze
2:00pm|Wolfensohn Hall and Remote Access

Sponsored by the Minerva Research Foundation. 

In 2014, Fargues realized that one can formulate the local Langlands correspondence over p-adic fields as a geometric Langlands correspondence on the Fargues-Fontaine curve. This raises the question of a...
