Deriving Effective PDEs from Many-Body Schrödinger Equations

November 28, 2024

In-person talk in ESB 4133

In this talk, we derive nonlinear Schrödinger equations and the Hartree equation as effective descriptions of the linear many-body Schrödinger equation. Starting with an introduction to the motivation and the mathematical framework, we will explore the Fock space formalism and the coherent state... Read more

The scaling limit of high-dimensional percolation

November 27, 2024

I will give an overview of forthcoming work proving that large critical percolation clusters in high-dimensional lattices converge under rescaling to the expected universal limit object: superBrownian motion. A key step is to compute the first-order asymptotics of k-point connection... Read more

Math-Bio: This Orchard is on Fire -- A Spatio-Temporal Model of Blossom Blight

November 27, 2024

ESB4133

Fire blight is a bacterial plant disease that affects apple and pear trees. We present a mathematical model for its spread in an orchard during bloom (sometimes referred to as blossom blight). This is a PDE-ODE coupled system, consisting of two semilinear PDEs for the pathogen, coupled to a... Read more

Equivariant unknotting numbers for strongly invertible knots

November 26, 2024

MATH 204

The unknotting number of a knot is the minimum number of times that the knot must be passed through itself in order to untie it. The unknotting conjecture states that the unknotting number of a knot obtained by tying two knots in sequence along a string is equal to the sum of the unknotting... Read more

Motivic cohomology in mixed-characteristic

November 25, 2024

Math 126

Motivic cohomology is a cohomology theory that can be defined internally within Grothendieck's category of motives. Voevodsky developed this theory for smooth varieties, demonstrating its profound connections to algebraic cycles and algebraic K-theory. However, its behaviour beyond the smooth... Read more

Problems arising (and some solutions) from Vogan's conception of the local Langlands correspondence

November 22, 2024

UBC

David Vogan's 1993 paper on the local Langlands correspondence showed that there are advantages to simultaneously considering representations of a p-adic group together with its pure inner forms. Combined with other insights, this opened the door to introducing ABV-packets for p-adic groups,... Read more

Relation between low-lying zeros and central values

November 22, 2024

Online

In practice, L-functions appear as generating functions encapsulating information about various objects, such as Galois representations, elliptic curves, arithmetic functions, modular forms, Maass forms, etc. Studying L-functions is therefore of utmost importance in number theory at large. Two... Read more
