This nicely summarises the basic idea of =E2=88=9E-categories, but th= ere is a large gap between this intuition and the definition(s) of =E2=88=9E-category one finds in the literature. The aim of these lectures i= s to fill this gap by answering the following question: What do we really mean by "spaces", and what sort of things do we want to do with them? Lecture 1: Homotopy groups and Whitehead's theorem Lecture 2: Kan complexes Lecture 3: Model categories Lecture 4: Homotopy commutative vs homotopy coherent Lecture 5: Quasi-categories via spines Lecture 6: Quasi-categories via inner horns Schedule: 31 Jan (Mon) 4-5pm (AEDT/GMT+11) 3 Feb (Thu) 4-5pm (AEDT/GMT+11) 7 Feb (Mon) 4-5pm (AEDT/GMT+11) 10 Feb (Thu) 4-5pm (AEDT/GMT+11) 14 Feb (Mon) 4-5pm (AEDT/GMT+11) 17 Feb (Thu) 4-5pm (AEDT/GMT+11) Held online via zoom at: https://anu.zoom.us/j/87221396938?pwd=3DazgxQmJWWWhtTUFHUGdpcXE2MGp6QT09 No registration required.
