Magnitude 2023

Since the first Magnitude workshop—held in Edinburgh, Scotland, in 2019—there have been many interesting developments in the study of magnitude and magnitude homology.

For instance, new perspectives on magnitude homology have recently established a valuable connection with the path homology of directed graphs [1]; analytic results concerning the magnitude function of Euclidean domains and Riemannian manifolds have opened up analogues, for magnitude, of classical problems in spectral geometry [2]; and researchers have begun to explore concrete applications of both magnitude and magnitude homology in topological data analysis. (For more, see the ever-growing Magnitude Bibliography.)

As the field continues to expand, Magnitude 2023 will bring us brought us together for a second time to share results, questions and ideas. The workshop will gather gathered researchers interested in magnitude along with experts in geometric analysis, topological dynamical systems, coarse geometry and other areas of mathematics where notions of size or dimension are important.

Magnitude 2023 will begin began in the late afternoon of Monday 4th December, with a talk by Tom Leinster at the Colloquium of the Osaka University Mathematics Department. The main part of the workshop will take took place on Tuesday 5th-Friday 8th December, with a free afternoon on Thursday 7th and a conference dinner that evening.

The schedule and the list of titles and abstracts are available now on the Programme page. Slides for some talks can be found on the Slides page. And you can read Tom Leinster's live-blog of the conference at the n-Category Cafe!
