Dear all, We are pleased to announce that pre-registration for the London Mathematical Society Research School "Bicategories, categorification and quantum theory”, to be held 11th-15th July 2022 at the University of Leeds, is now open. The school will include mini-courses on Bicategories (Richard Garner, Macquarie University), Monoidal categories like that of Hilbert Spaces (Chris Heunen, University of Edinburgh), Categorification (Marco Mackaay, University of Algarve) and Hopf Algebras (Sonia Natale, Universidad National de Córdoba), as well as tutorials. You can pre-register by visiting the web page https://conferences.leeds.ac.uk/bcqt2022/ and following the relevant link. The deadline for pre-registration is Friday 29th April 2022. The pre-registration form allows you also to apply for financial support. After the deadline, the organizing commitee will review pre-registrations and provide instructions to complete registration. At present, the plan is to hold the school entirely in-person, with a maximum number of participants set at 50. With best regards, Nicola Gambino, Vanessa Miemietz, Jamie Vicary [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
