Gray categories with duals and their diagrams

Abstract: Gray categories with a coherent notion of duals are captured well by a calculus of three-dimensional diagrams, generalising the familiar string diagrams for braided categories. The talk will discuss what is in the paper with this title (Advances in Mathematics, Volume 450, 2024, 109740), what got left out, and what is still missing.
