Title: Toda Brackets in Quasi-Categories

Abstract: Toda Brackets are obstructions to rectifying certain kinds of homotopy commutative diagrams of topological spaces. They were originally introduced by Toda to study unstable homotopy groups of spheres. Baues, Blanc and their collaborators gave a more general definition of Toda brackets in pointed simplicial (model) categories. This talk will explain how to generalise this further to cover unpointed simplicial categories and quasi-categories. One of the major goals of this project is to describe the differentials in spectral sequences in a quasi-category.
