Applied Topology

I’m very pleased to announce the VSU-CBMS Conference on Topological Data Analysis and Persistence Theory, which will take place August 8–12, 2022 at Valdosta State University (GA, USA).   

This conference features Dr. Peter Bubenik (U. of Florida), who will give a series of daily lecturers on TDA and Persistence Theory.

Please direct any questions to Dr. Jose A. Velez ([email protected]) or myself ([email protected]). 

Deadline for registration: April 29th

Thank you!

We invite the Topological Data Analysis community to a book launch event for Gunnar Carlsson’s and Mikael Vejdemo-Johansson’s new book Topological Data Analysis with Applications. At the event, Justin Curry (SUNY Albany) will lead a fireside chat with Mikael Vejdemo-Johansson in a conversation about the research field, its history, community, and wider applicability. Copies of the book will be available to browse through, and participants interested in buying a copy can prepay at a discounted price of $40 (tax included). Prepaid books will be signed and delivered at the event.

CUNY requires all campus visitors to be fully vaccinated. In order to issue campus access passes, we need RSVP in advance.

When? Friday April 8, 5pm-7pm
Where? CUNY Graduate Center, 365 5th Avenue, NYC; Room 4201.
Order book by? March 24
RSVP by? March 29

RSVP and prepay here: https://www.eventbrite.com/e/book-launch-topological-data-analysis-with-applications-tickets-290959907917

After the event finishes, we are planning an afterparty at some cocktail bar in NYC. Indicate your interest with your RSVP.

The Vrije Unversiteit Amsterdam is advertising two tenure track positions. From the advertisement:

Our department is looking for mathematicians with a proven expertise in geometric and topological aspects of data and algorithms. This topic can be interpreted in a wide sense: we are interested in analytical, statistical, probabilistic and combinatorial ideas to deepen our understanding of the relation between geometric and topological ideas on the one hand, and data science and its algorithms on the other hand. Concrete subject fields include stochastic geometry, topological (methods in) data analysis, geometric aspects of statistical learning, reconstruction of manifolds from data, equivariant deep neural networks, and applications of these. Other combinations of geometry/topology and data/algorithms are also a possibility. In this position, you develop their own research line. The position of Assistant Professor is initially a tenure track position for five years. After four years, based on transparent criteria, we will take a decision on the tenure. The preferred starting date is on or before September 1, 2022.

Dear Colleagues, 

We are happy to announce the online workshop Bridging Applied and Quantitative Topology, to take place virtually during the week of May 9-13, Monday to Friday, 2022:

https://sites.google.com/view/applied-quantitative-topology/

Topics of interest include Vietoris-Rips complexes, nerve lemmas, manifold reconstruction, Kuratowski embeddings, metric thickenings, the tight span, the filling radius, Gromov-Hausdorff distances, optimal transport, homotopies of bounded size, geometric group theory, topological combinatorics, geometric topology, etc., and this is far from an exhaustive list. This workshop is co-hosted by the Applied Algebraic Topology Research Network (AATRN) and the TGDA Group at The Ohio State University.

Most days of the workshop will consist of three 35 minute long talks (in 50-minute slots), 8am-11am Eastern Daylight Time = 2pm-5pm Central European Summer Time. Each talk will be followed by a discussion period intended to foster a productive conversation between the speaker and the audience.

In addition to invited talks, there will be a virtual poster session on Wednesday, May 11, at 9am Eastern Daylight Time = 3pm Central European Summer Time. Early career researchers are especially encouraged to participate. The registration form to contribute to the poster session will be open until Wednesday, April 20, at the following link: https://forms.gle/ZbpTKJCBRntSJavW7.

A list of confirmed speakers is available at

We hope to see you there!

We added a new channel for basic geometry & topology questions to the popular Slack workspace “Geometry & Topology in ML”. Despite the name of the workspace, there is no machine learning background needed for this particular channel. We are looking forward to your questions and answers. 

To see/write messages in this new channel, you need to join the whole Slack workspace “Geometry & Topology in ML”: Invite link
You can afterwards subscribe/unsubscribe to/from the various channels according to your interest.

Example questions:

1. Why do we need assumption X in Theorem Y? What would be a counterexample?
2. What is a good reference for reading up on a sheaf theoretic approach to persistent homology?
3. I read about algorithm X, and understand every line, but lack intuition: What is the big picture idea behind it?

We hope this new channel will be a nice addition to the already existing geometry and topology Q&As (This list undoubtedly has unintentional omissions; please let us know if you have recommended additions):

– https://mathoverflow.net/ (with different tags for different sub-fields of mathematics)
– https://math.stackexchange.com/ 
– https://cs.stackexchange.com/, https://cstheory.stackexchange.com/ 
– The ALGTOP-L discord: https://discord.com/invite/sTHgwsKVQd 
– There are a variety of webpages and list-servs, such as https://appliedtopology.org/, ALGTOP-L, WinCompTop, compgeom-announce, that sometimes have geometry and topology Q&As, but are more focused on announcements (conferences, job postings, etc).
– …

We want to encourage people who are rather new to (applied/computational) geometry and topology, in particular, to ask questions!

Best wishes,
Bastian Rieck, Niklas Hellmer, Teresa Heiss

I would like to bring four vacancies at Utrecht University in the Netherlands to your attention. Two of these are joint with the computer science department; possible themes include (but are not limited to) topological data analysis and homotopy type theory. Two further positions are joint with the physics department; possible themes include (but are not limited to) topological or conformal field theory or the study of topological phases of matter. In general, if your research touches physics or computer science, please do not hesitate to apply. 

The level of the positions is up to negotiation, ranging from a 5-year lecturer/researcher position to an associate professorship. The application deadline is March 14.
