Dear friends and colleagues, We're delighted to announce the Applied Category Theory 2018 Adjoint School, an initiative to bring early career researchers into the applied category theory community. The Adjoint School comprises two phases: (1) an online reading seminar based on the recent Kan Extension Seminars, and (2) a four day research week at the Lorentz Center, Leiden, The Netherlands. Participants will also be invited to attend Applied Category Theory 2018, which will be held immediately following the research week, also at the Lorentz Center. During the school, participants will work under the mentorship of four mentors, on one of the following research projects: - John Baez: Semantics for open Petri nets and reaction networks - Aleks Kissinger: Unification of the logic of causality - Martha Lewis: Compositional approaches to linguistics and cognition - Pawel Sobocinski: Modelling of open and interconnected systems The online seminar begins in early January 2018, and will run until the research week begins on April 23rd, 2018. Applied Category Theory 2018 will be held April 30th to May 4th. Applications to participate in the school are now open. For more details, including how to apply, please see here: http://www.appliedcategorytheory.org/school or contact the organisers below. Applications close November 1st.
