Affiliated Activities

AATRN hosts two affiliated seminars: a seminar on topological complexity, and a seminar on Vietoris-Rips theory. We have also hosted talks from ATMCS. Click on the relevant subpages for more information.

Workshops and Conferences

Workshop on Bridging Applied and Quantitative Topology

This workshop on Bridging Applied and Computational Topology, which is associated with the Vietoris-Rips seminar, is scheduled for the week of May 9-13, 2022, at 8am-11am Eastern Daylight Time (UTC-4). This workshop is organized by Henry Adams, Johnathan Bush, Sunhyuk Lim, and Facundo Mémoli.

Talks co-hosted by AATRN and ATMCS

These talks were contributed and accepted for ATMCS 9 in 2020, but this was not ATMCS itself (which was cancelled or postponed). The talk schedule spanned Summer 2020 and January 2021. Recordings can be found here.

This is a public database of real-world applications of TDA. The papers are exportable in various formats. There are three main labels (starting with 1 -, 2-, and 3 -) which explain the application areas, the mathematical tools used and the type of the inputs. In addition, some papers have the label innovate/confirm which says if the information extracted is novel (in some sense) or confirms the ones found by other (preexisting) methods. Please notify Barbara Giunti (bgiunti(at) if anything should be added or updated, or if you want to join and contribute!
