The birational geometry of GIT quotients

Bulletin of the London Mathematical Society, EarlyView.
Abstract Geometric invariant theory (GIT) produces quotients of algebraic varieties by reductive groups. If the variety is projective, this quotient depends on a choice of polarisation; by work of Dolgachev–Hu and Thaddeus, it is known that two quotients of the same variety using different polarisations are related by birational transformations.

Removing scalar curvature assumption for Ricci flow smoothing

Bulletin of the London Mathematical Society, EarlyView.
Abstract In recent work of Chan–Huang–Lee, it is shown that if a manifold enjoys uniform bounds on (a) the negative part of the scalar curvature, (b) the local entropy, and (c) volume ratios up to a fixed scale, then there exists a Ricci flow for some definite time with estimates on the solution assuming that the local curvature concentration is small ...

A Longitudinal Teacher Case Study on the Development of Creative Self‐Regulation and Agency

The Journal of Creative Behavior, Volume 59, Issue 2, June 2025.
ABSTRACT Creative self‐regulation (CSR) is important in facing the challenges and uncertainty of creative teaching and learning. Our understanding for how teachers develop creative self‐regulation skills and knowledge for the classroom remains limited. This longitudinal case study begins to fill this gap with an in‐depth investigation of one U.S.

Recommendations Based on Experiences of Pandemic‐Led Remote Mathematics Teaching in Pre‐K–12 Contexts: A Systematic Review From the Activity Theory Perspective

Journal of Computer Assisted Learning, Volume 41, Issue 3, June 2025.
ABSTRACT Background In the aftermath of the COVID‐19 pandemic, it is critical to reflect holistically on the experiences gained in the past few years. We thus review research on remote mathematics teaching in Pre‐K–12 contexts, utilising Activity Theory as a theoretical lens for research synthesis.
