Probability Seminar

Topic #1 (Wang): Holography of the Loewner Energy; Topic #2 (Hutchcroft): Critical Behaviour in Long-Range and Hierarchical Percolation
Yilin Wang; Tom Hutchcroft
10:15am|Simonyi 101 and Remote Access

Topic #1 (Wang): The Loewner energy is a Möbius invariant quantity that measures the roundness of Jordan curves on the Riemann sphere. It arises from large deviation deviations of SLE0+ and is also a Kähler potential on the Weil-Petersson...

Quivers, Flow Trees and Log Curves
Pierrick Bousseau
9:15am|Remote Access

Donaldson-Thomas (DT) invariants of a quiver with potential can be expressed in terms of simpler attractor DT invariants by a universal formula. The coefficients in this formula are calculated combinatorially using attractor flow trees. In joint...

Arithmetic of critical p-adic L-functions
Kazim Buyukboduk
4:30pm|Princeton University, Fine Hall 214

In joint work with Denis Benois, we give an étale construction of Bellaïche's p-adic L-functions about θ-critical points on the Coleman–Mazur eigencurve. I will discuss applications of this construction towards leading term formulae in terms of p...

Mathematical Conversations

William Thomson, Oliver Heaviside and the Transatlantic Cable
6:00pm|Rubenstein Commons | Meeting Room 5

As telegraph lines proliferated through Europe and North America in the 1850s, plans were drawn up for a transatlantic telegraph cable.  Extended telegraph lines were modelled by William Thomson (Lord Kelvin), who showed that a transatlantic cable...

Generalized Entropy Methods and Stability in Sobolev and Related Inequalities
Jean Dolbeault
3:00pm|Simonyi Hall 101 and Remote Access

This lecture is devoted to a survey on explicit stability results in Gagliardo-Nirenberg-Sobolev and logarithmic Sobolev inequalities. Generalized entropy methods based on carré du champ computations and nonlinear diffusion flows can be used for...

Special Year Research Seminar

The Factorial Function and Generalizations, Revisited.
3:30pm|Simonyi 101 and Remote Access

In 1996 Manjul Barghava introduced a notion of P-orderings for arbitrary sets S of a Dedekind domain, with respect to a prime ideal P, which defined associated invariants called P-sequences. He combined these invariants to define generalized...

Updates on the Lipschitz Extension Problem
10:30am|Simonyi Hall 101 and Remote Access

The Lipschitz extension problem is the following basic “meta question” in metric geometry:  Suppose that X and Y are metric spaces and A is a subset of X. What is the smallest K such that every Lipschitz function f:A\to Y has an extension F:X\to Y...
