Idea

The term higher structure (as used in numerous conference titles in recent years, e.g. CGX 11, BBM 16, SBBM 18, JSSW 18 and by a journal Higher Structures) has come to mean essentially what elsewhere was and is called categorified mathematical structure or mathematical structure in higher category theory, or, more specifically, mathematical structure in (∞,1)-category theory, hence mathematical structure in homotopy theory (higher algebra/homotopical algebra, higher geometry/derived geometry, etc.).

For example, L-∞ algebras, which are Lie algebra objects in the (∞,1)-category of chain complexes, would be a core topic in higher structures in Lie theory (elsewhere: ∞-Lie theory).
