The aim of this meeting is to stimulate interaction between people, who are working in higher structures interpreted in the broad sense (to mean higher stacks, L-infinity- and A-infinity-algebras, Batalin-Vilkovisky algebras, higher category theory, operad theory and related areas). Such flavours of higher structures have appeared in

• differential geometry (non-abelian and higher gerbes),
• rational homotopy theory,
• algebraic topology (string structures, extended topological quantum field theories),
• persistent homology,

and have found a number of applications in mathematical physics, such as

• higher gauge theory,
• topological quantum field theory, possibly with defects,
• homological methods in quantum field theory,
• strings and branes,
• topological phases of matter,

among others.
