# 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.

## Seminars

## Workshops and Conferences

### Workshop on *Bridging Applied and Quantitative Topology*

*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.

We also host recorded videos from the following conferences on our **YouTube channel**:

## Unaffiliated Activities

You may be interested in the following other resources that are not organized by AATRN:

Other online research seminars on applied topology include GEOTOP-A: Applications of Geometry and Topology and the Asia Pacific Seminar on Applied Topology and Geometry (APATG).

An important source of applied topology news is appliedtopology.org. Mailing lists with announcements in applied topology include WinCompTop and ALGTOP-L and compgeom-announce. You may also be interested in joining the Slack channel "Geometry & Topology in ML" via their invite link.

Check out the database of articles on real-world applications of TDA, run by Barbara Giunti and Jānis Lazovskis!
