The High-Dimensional Approximation (HDA) Workshop is a series of biennial international meetings covering current research on problems related to high-dimensional approximation. The previous workshops in the series were held at the Australian National University in Canberra (HDA 2005, HDA 2007, HDA 2013, and HDA 2023), at the University of New South Wales in Sydney (HDA 2009 and HDA 2017), at the ETH Zurich (HDA 2019), and at the University of Bonn (HDA 2011, HDA 2015, and HDA 2025).
The 11th Workshop (HDA 2027) on High-Dimensional Approximation covers a range of topics central to modern high-dimensional approximation and their applications. The workshop will provide an interactive forum for researchers interested in topics ranging from high-dimensional approximation theory over computational methods to engineering and scientific applications.
Workshop format. Each speaker will give a 30-minute talk.
All presenters and participants must register by 31 December 2026 in order to be included in the conference program. University of Sydney staff and students wishing to attend the conference, please contact by 31 December 2026 the conference organisation.
For speakers: Abstracts can be added up to 15 January 2027 by emailing the conference organisation
For research students: supportive letter from supervisor must be provided at time of registration by emailing the conference organisation.
Workshop Format: No invited talks. Each speaker will give a 30-minute talk.
All participants are responsible for ensuring they obtain the correct visa prior to travel. Most participants should be able to apply for a visitor visa (such as eVisitor) but please confirm the appropriate visa for your circumstances using the Australian Government Visa Finder.
Visa processing times vary. Participants are strongly advised to apply as early as possible, and ideally no later than 2–3 months prior to travel. Please note, a formal invitation letter is not required for these visas. Your registration confirmation and tax invoice are typically sufficient documentation. Conference organisers are unable to provide any further immigration advice.
Welcome to Sydney. The conference will be held at the University of Sydney campus. If you are arriving from interstate or overseas, here is some information reaching to/from Sydney airport. You can find your way to the conference using the campus map.
You can find out more about accommodation and restaurants in the area from the following links: restaurants on campus, accommodation (we recommend you book directly with the hotel), and how to get to the University campus.
Every room is equipped with a desktop computer and a projector. If you want to use your own laptop, please check connection in advance and bring any required connectors/adaptors to your talk, if necessary, as we cannot supply them.
