Gambino, N orcid.org/0000-0002-4257-3590 and Larrea, MF (2023) Models of Martin-Löf Type Theory from Algebraic Weak Factorisation Systems. The Journal of Symbolic Logic, 88 (1). pp. 242-289. ISSN 0022-4812
Abstract
We introduce type-theoretic algebraic weak factorisation systems and show how they give rise to homotopy-theoretic models of Martin-Löf type theory. This is done by showing that the comprehension category associated with a type-theoretic algebraic weak factorisation system satisfies the assumptions necessary to apply a right adjoint method for splitting comprehension categories. We then provide methods for constructing several examples of type-theoretic algebraic weak factorisation systems, encompassing the existing groupoid and cubical sets models, as well as new models based on normal fibrations.
