PIMS Workshop on Arithmetic Topology

  • Start Date: 06/10/2019
  • End Date: 06/14/2019

University of British Columbia


The last 10 years have brought a burst of activity at the intersection of algebraic topology, number theory and algebraic geometry. This has led to a wealth of:


  • New theorems, such as Ellenberg–Venkatesh–Westerland’s proof of the Cohen–Lenstra heuristics for function fields;
  • New sources of heuristics in topology, such as Vakil–Wood’s predictions from the Grothendieck ring, or the notion and coincidences of homological densities as in Farb– Wolfson–Wood;
  • Refinements of classical enumerative theorems using modern topological tools, such as Kass–Wickelgren’s arithmetic count of the 27 lines on a cubic surface; and
  • A renewed focus on unstable homology, as in Galatius–Kupers–Randal-Williams and Miller–Wilson. We believe that these results are just the beginning of the emerging area of arithmetic topology.



This 5 day workshop will bring together junior and senior researchers from across these areas with the goal of:

1) giving participants a global view of a fast emerging and multidisciplinary area,

2) giving participants a detailed awareness on the range of methods available, and

3) emerging with a robust problem list which can help guide activity in the area for the next 5-10 years.
