Deformations of Special Structures in Dimensions 6 and 7

March 28, 2025

ESB 2012 and Zoom

Conifold transitions are a mechanism in which a Calabi-Yau 3-fold is deformed into another by contracting curves and smoothing out the resulting conical singularities. Reid's Fantasy conjectures that all Calabi-Yau 3-folds can be linked by a sequence of these transitions. It is further... Read more

Transversal projections of fractals

March 26, 2025

2207 Main Mall

The orthogonally projected shadows of a dispersed set in the plane carry much of the information about the shape of the set. The average size of the shadow, known as the Favard length, can be used to study density, structure, distribution, rectifiability, and complex analytical properties such... Read more

The scaling limit of the high-dimensional Ising model is the Gaussian free field

March 26, 2025

In two independent papers, Aizenman and Fröhlich argued that every scaling limit of the critical Ising model in dimensions $d>4$ is trivial (or Gaussian). This qualitative result can be reformulated as follows: the Schwinger functions of any (reasonable) scaling limit satisfy Wick’s law. This... Read more

Math-Bio: Harnessing Mathematical Modeling and Epidemiological Data for Infectious Disease Surveillance and Public Health Decision Making

March 26, 2025

ESB4133

Mathematical modeling, when combined with diverse epidemiological datasets, provides valuable insights for understanding and controlling infectious diseases. In this talk, I will present a series of case studies demonstrating how the synergy between modeling and serological, case-based, and... Read more

2-cell embeddings of cubic graphs

March 25, 2025

ESB 4133 (PIMS library)

Given a graph G, its genus distribution is the sequence whose k-th term is the number of 2-cell embeddings of G in the orientable surface of genus k. The Log-Concavity Genus Distribution (LCGD) Conjecture states that the genus distribution of every graph is log-concave. This has been proven to... Read more

Zeta functions of algebraic varieties and special values

March 24, 2025

Math 126, UBC Math department

In 1966, Tate proposed the Artin-Tate conjectures, which expresses special values of zeta function associated to surfaces over finite fields. Conditional on the Tate conjecture, Milne–Ramachandran formulated and proved similar conjectures for smooth proper schemes over finite fields. The... Read more

UBC/PIMS Early Career Award Lecture

March 21, 2025

ESB 2012 and Zoom

Deep learning models are often seen as black boxes, their complexity stemming from integrating numerous architectural components across multiple layers while being trained on high-dimensional datasets with carefully tuned hyperparameters. In this talk, I will present recent work uncovering... Read more

Martingale and analytic dimensions coincide under Gaussian heat kernel bounds

March 19, 2025

Given a strongly local Dirichlet form on a metric measure space that satisfies Gaussian heat kernel bounds, we show that the martingale dimension of the associated diffusion process coincides with Cheeger's analytic dimension of the underlying metric measure space. More precisely, we show that... Read more

Math-Bio: Analysis of a 3-component reaction-diffusion system with linear cross-diffusion

March 19, 2025

ESB4133

In this talk, I will present a roadmap for deriving minimal necessary conditions for diffusion-driven instability for a 3-component reaction-diffusion system with linear cross-diffusion. For the reaction kinetics, we postulate and formulate a new 3-component phenomenological molecular... Read more
