Diagram Categories in Homotopy Theory

2025 — 2028

This CRG will study diagram categories in homotopy theory, focusing on functor calculus, equivariant
homotopy theory, and polyhedral products. These are active and important fields of research with
connections to each other and to other areas of mathematics. We have strong research groups in homotopy
theory within the PIMS network, and the CRG will strengthen connections among these groups, enhance
their impact in other areas of mathematics, provide training for junior mathematicians, and produce
world-class research outputs.

 

The planned activities include a summer school, several workshops and minischools, and an international
research conference. We also request funding for one Postdoctoral Fellow and a number of research visits.

Summer School on Homotopy Colimits
June 22–26, 2026
University of Regina
Homotopy limits and colimits are a fundamental tool in homotopy theory, with applications to topology, geometry, and algebra. The event is aimed at graduate students, postdocs, and early-career researchers who want to learn more about this topic. The...
