Computer Science/Discrete Mathematics Seminar I

Efficient Verification of Computation on Untrusted Platforms
Yael Kalai
11:15am|Simonyi 101 and Remote Access

Efficient verification of computation is fundamental to computer science and is at the heart of the P vs. NP question. Recently it has had growing practical significance, especially with the increasing popularity of blockchain technologies and cloud...

Special Joint IAS/Princeton University Symplectic Geometry Seminar

Non-standard Contact Structures on Spheres and Applications
9:45am|Simonyi Hall 101 and Remote Access

In this talk, I will describe the construction of contact structures on higher-dimensional spheres with exotic fillability properties. These can then me implemented on more general manifolds via connected sum, yielding a host of exotic higher...

Joint IAS/PU Number Theory Seminar

Regular de Rham Galois Representations in the Completed Cohomology of Modular Curves
Lue Pan
4:30pm|Princeton University, Fine 214

Let p be a prime. I want to explain how to use the geometry of modular curves at infinite level and the Hodge–Tate period map to study regular de Rham p-adic Galois representations appearing in the p-adically completed cohomology of modular curves...

On Crossing Probabilities in Critical Random-Cluster Models
Eveliina Peltola
11:15am|Simonyi 101 and Remote Access

I will discuss exact solvability results (in a sense) for scaling limits of interface crossings in critical random-cluster models in the plane with various general boundary conditions.

The results are rigorous for the FK-Ising model, Bernoulli...

David White (North Carolina State University):  Symplectic Instanton Homology of Knots and Links in 3-manifolds

Powerful homology invariants of knots in 3-manifolds have emerged from both the gauge-theoretic and the symplectic kinds of Floer theory...

Mathematical Conversations

Nothing Matters
6:00pm|Birch Garden, Simons Hall

In the second half of the 19th century, it was discovered that algebra and geometry had nothing to do with each other. I will discuss this fact and some consequences.

Analysis and Mathematical Physics

On Co-dimension One Stability of the Soliton for the 1D Focusing Cubic Klein-Gordon Equation
3:00pm|Simonyi Hall 101 and Remote Access

Solitons are particle-like solutions to dispersive evolution equations whose shapes persist as time evolves. In some situations, these solitons appear due to the balance between nonlinear effects and dispersion, in other situations their existence...

A Useful Lemma about Intersections of Sets and Some Applications
10:30am|Simonyi 101 and Remote Access

The "intersectivity lemma" states that if a ∈ (0,1) and A_n, n ∈ N,  are measurable sets in a probability space (X,m) satisfying  m(A_n) ≥ a for all n, then there exist a subsequence n_k, k ∈ N, which has positive upper density and such that the...

Special Year Research Seminar

Infinite Partial Sumsets in the Primes
2:00pm|Simonyi 101 and Remote Access

It is an open question as to whether the prime numbers contain the sum A+B of two infinite sets of natural numbers A, B (although results of this type are known assuming the Hardy-Littlewood prime tuples conjecture).  Using the Maynard sieve and the...
