## Abstract

The key open problem of string theory remains its non-perturbative completion to M-theory. A decisive hint to its inner workings comes from numerous appearances of higher structures in the limits of M-theory that are already understood, such as higher degree flux fields and their dualities, or the higher algebraic structures governing closed string field theory. These are all controlled by the higher homotopy theory of derived categories, generalised cohomology theories, and L_{∞}-algebras. This is the introductory chapter to the proceedings of the LMS/EPSRC Durham Symposium on ‘Higher Structures in M-Theory’:. We first review higher structures as well as their motivation in string theory and beyond. Then we list the contributions in this volume, putting them into context.
