(NCATLAB)
This is a wiki for collaborative work on Mathematics, Physics, and Philosophy — especially (but far from exclusively) from the higher structures point of view: with a sympathy towards the tools and perspectives of homotopy theory/algebraic topology, homotopy type theory, higher category theory and higher categorical algebra.
