Generalized Chevalley criteria in simplicial homotopy type theory

Published 13 Mar 2024 in math.CT, cs.LO, math.AT, and math.LO | (2403.08190v1)

Abstract: We provide a generalized treatment of (co)cartesian arrows, fibrations, and functors. Compared to the classical conditions, the endpoint inclusions get replaced by arbitrary shape inclusions. Our framework is Riehl--Shulman's simplicial homotopy type theory which supports the development of synthetic internal $(\infty,1)$-category theory.
