motivation

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 low-dimensional geometry and topology, and on the development of practical algorithms and their implementation. This is an area with an abundance of computational and algorithmic challenges, where practical solutions to many solvable problems, such as the homeomorphism problem, remain elusive. 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 have introductory talks on the first three days of the workshop, followed by research talks on the remaining two days.

The timing for this workshop is chosen to allow participants at SoCG 2017 two days for collaboration, sight seeing and travel to Brisbane!

introductory lectures

Serge Gaspers: Parameterised complexity
Monique Teillaud: Delaunay triangulations
Vanessa Robins: Discrete Morse theory

registration

Please register by e-mailing stephan.tillmann@sydney.edu.au with the following information:
  • Which days will you participate in the workshop?
  • Will you attend the conference dinner on Friday evening?
  • Are you a student?
A small fee will be collected at the event to contribute towards catering costs (AUD 20 for AMSI members and AUD 25 for non-AMSI members) and (if applicable) the conference dinner (around AUD 50, BYO). Reduced fees apply to students. Details on the conference dinner can be found in the program.

We hope to see you in June!
–Josh, Robert and Stephan

accommodation

You can book rooms at the Best Western Haven Glebe in Glebe with the University special rate of AUD 155/night. Just mention that you participate at a workshop here.

support

Australia: Students or early career researchers from AMSI member universities without access to a suitable research grant or other source of funding may apply (with approval of their Head of Mathematical Sciences) for subsidy of travel and accommodation out of their departmental travel allowance.

USA: Students or early career researchers based in the USA and participating at SoCG may apply for NSF funding. Here are instructions on how to apply. The deadline (including supporting letters) is 19 May 2017. All students and postdocs (at US institutions) are encouraged to apply, but priority will be given to speakers (either at the Symposium proper, at the Young Researchers Forum, or at another satellite workshop) who have no (or limited) other travel funding.

statement of inclusiveness

CATS 2017 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."
