Dear all,

We would like to announce the Conference on the Mathematics of Complex Data in Stockholm on June 13-16, 2022, hosted by the Brummer & Partners MathDataLab at the Department of Mathematics at KTH Royal Institute of Technology in Stockholm.

The aim of the conference is to bring together leading experts in the field and highlight recent advances in mathematics related to data analysis and artificial intelligence. The conference is intended to cover a broad range of topics with emphasis on data analysis, including algebra and topology, probability and statistics, applied harmonic analysis, and optimization.

The following is a snippet of topics covered at the conference.
* Algebraic statistics
* Applied harmonic analysis
* Computational methods for complex data
* Control and optimisation in machine learning
* High-dimensional statistics
* Mathematics of deep learning
* Stochastic analysis in learning
* Topological data analysis

The list of our speakers includes Patrick Cheridito (ETH, Zurich), Anna Gilbert (University of Michigan), Kathryn Hess Bellwald (EPFL), Mauro Maggioni (Johns Hopkins University), Eric Moulines (Ecole Polytechnique), Bernd Sturmfels (Berkeley/MPI Leipzig), Joel Tropp (Caltech), and Sara van de Geer (ETH, Zurich).

The registration is open. For more details see https://www.mathdatalab.org/ .

We will also organize a poster session. You are very welcome to apply for contributing by presenting your poster. We are preparing a book of abstracts for the conference. To be included, we need the applications for the poster by April 30.
Here is a link to the application for the poster session: https://docs.google.com/forms/d/e/1FAIpQLSej0C68CEAZmdctAaAcq-TQ8fhQiJ7rIjZzdBg-eX6IoTrXsw/viewform?usp=pp_url

We are excited to welcome you to Stockholm this summer!

Best wishes from the organizing team, René Corbet

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 

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

We hope to see you there!

The organizers,

Henry Adams, Johnathan Bush, Sunhyuk Lim, and Facundo Mémoli

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.

We are organizing a single day online workshop, titled Algebraic 
Combinatorics and Category Theory in Topological Data Analysis. This will take place on Saturday, March 12, 2022. This workshop is a substitute for a special session in the cancelled AMS Spring Southeastern Sectional Meeting. The webpage is https://sites.google.com/view/tda-alg-combi-cat/home

We plan to start at 8:50am Eastern Time (= 2:50pm Central European Time). Zoom coordinates and a detailed timetable will be released on the webpage several days beforehand. We hope to meet many friends and colleagues on March 12!
