Representation theory's hidden motives
27 September - 1 October 2021
In recent years, motivic techniques have been applied in several branches of representation theory, for example in geometric and modular representation theory. The goal of this workshop is to bring together researchers in these areas in order to foster new synergies in topics such as foundational aspects of the theory of motives, Tate motives on varieties of representation-theoretic origin, motivic aspects of the Langlands program, and motives of classifying spaces.
All participants are required to confirm their immunisation status (via vaccination or convalescence) or present a negative test result obtained from a certified testing centre within the last 48 hours ("3 G rule").

Support and child care
The Cluster of Excellence offers limited support for PhD students and early PostDocs. Child care is available free of charge for all participants of the workshop.
Because of the lockdown in Sydney, the Sydney venue has been closed. We will facilitate the exchange between all people attending the conference using a dedicated chat room called gather town. See the schedule sent to participants for details.
You are welcome to download the conference poster and display it at your institution.
