An intrinsic homotopy theory for simplicial complexes, with applications to image analysis
Marco Grandis
A simplicial complex is a set equipped with a down-closed family of distinguished finite subsets. This structure, usually viewed as codifying a triangulated space, is used here dir…

Higher fundamental functors for simplicial sets
Marco Grandis
This is a sequel to a previous paper, developing an intrinsic, combinatorial homotopy theory for simplicial complexes; the latter form the cartesian closed subcategory of 'simple p…
