Descent in the logarithmic étale topology

May 6, 2025

MATH 104

The logarithmic étale topology permits a logarithmic scheme to see the topology of a nearby family that has been punctured along the support of the logarithmic structure. This remarkable property allows a logarithmic scheme to see the nearby fiber of a degeneration, without requiring an explicit... Read more

The Good, The Bad, and The Ugly: Empowering Communities to Cultivate Mathematical Minds

May 6, 2025

MATH 225

This presentation explores the current state of mathematics education, highlighting the transformative potential of math circles and collaborative teaching alongside the challenges posed by systemic barriers and restrictive policies. We argue that true mathematical empowerment requires a shift... Read more

Elastic boost: an ideal non-linear rheology for particle manipulation and sorting

May 6, 2025

MATH 203

Particle sorting and manipulation have applications in a wide range of fields, from pharmaceutical sciences to biomedical and material engineering. It has been shown that the non-linearity in the background fluid flow, either coming from the fluid inertia or from the non-Newtonian rheology of... Read more

Local Regularity in the Navier-Stokes Equations

May 6, 2025

MATH 105

In this short talk, I will review several results on the local-in-space, short-time regularity of the Navier-Stokes equations with critical initial data. An application is the concentration behavior near potential blow-up points.

Sheng Hao Yang is currently pursuing a PhD in... Read more

Gradient estimates for Stokes equations near curved boundary

May 6, 2025

MATH 105

We show that the gradient of velocity is bounded in $L^q$ up to the boundary for weak solutions of Stokes equations with Navier BC and curved boundary, whose correctness has already been shown near the flat boundary by us in the previous work [CPAA 2024]. We also prove the corresponding high... Read more

Moments of Rankin-Selberg $L$-functions in the prime-power level aspect

May 6, 2025

MATH 204

In this talk we discuss joint work with Fatma Çiçek on establishing asymptotic formulae with power saving error term for first and second moments of Rankin-Selberg $L$-functions $L(1/2+i\mu,f\otimes g)$ where $f$ varies over newforms of conductor $p^n$ with $p$ being a fixed prime and $n\to\...
