On the collapsing of Calabi-Yau manifolds and Kähler-Ricci flows
Yang Li, Valentino Tosatti
We study the collapsing of Calabi-Yau metrics and of Kahler-Ricci flows on fiber spaces where the base is smooth. We identify the collapsed Gromov-Hausdorff limit of the Kahler-Ric…

Hybrid Goldstone Modes from the Double Copy Bootstrap
Yang Li, Diederik Roest, Tonnis ter Veldhuis
We perform a systematic classification of scalar field theories whose amplitudes admit a double copy formulation and identify two building blocks at 4-point and 13 at 5-point. Usin…

A new approach to the genus spectra of abelian -groups
Haimiao Chen, Yang Li
Given a finite group , the {\it genus spetrum} of is the set of integers such that can act faithfully on an orientable closed surface of genus $g…
