Speaker: Nick Hu (University of Oxford) Title: homotopy.io: a proof assistant for finitely-presented globular n-categories
Abstract: String diagrams present a convenient calculus for monoidal categories which appeal to topological intuitions and quotient out 'bureaucratic' coherence data. When regions are coloured (i.e. information-carrying), they analogously provide a graphical calculus for bicategories. Generalising, n-categories are difficult to define and manipulate algebraically, but intuitively correspond to an n-dimensional string diagram calculus. For n > 3, manipulating n-dimensional string diagrams quickly becomes unwieldy and error-prone. Towards this aim, we introduce the proof assistant homotopy.io.
