Computational & Algorithmic Topology, Sydney

The University of Sydney

Sydney, Australia

19 July - 23 July 2021 (online) & November/December 2021 (live talks, TBA)


This workshop at The University of Sydney will bring together experts and emerging researchers from Australia, the USA and Europe to report on recent results and explore future directions in computational and algorithmic topology and related areas. There will be a focus on problems in discrete geometry and computational topology. This workshop aims to stimulate interaction between researchers in order to bring about new collaborations on difficult problems that cannot be tackled from one viewpoint alone.

We plan to run this workshop in a hybrid format that includes prerecorded talks, followed up by problem sessions and live Q&A sessions with the speakers, as well as streamed talks given live via the ACE network.


July 2021:

Pre-recoded or live talks accompanied by working groups and live Q&A sessions

November/December 2021:

Live talks in Sydney (and streamed via the ACE network)

Statement of inclusiveness

CATS 2021 endorses this statement of inclusiveness and is a participating conference:

"We are a group of scholars, researchers, and teachers. We refuse to compromise the ideals of academic freedom and open exchange. We affirm that scientific events have to be open to everybody, regardless of race, sex, religion, national origin, sexual orientation, gender identity, disability, age, pregnancy, immigration status, or any other aspect of identity. We believe that such events have to be supportive, inclusive, and safe environments for all participants. We believe that all participants are to be treated with dignity and respect. Discrimination and harassment cannot be tolerated. We are committed to ensuring that the scientific events in which we participate follow these principles, and we request that organizers of scientific events make explicit statements on the event website to that effect."
