A Toolkit for Structured Lifts

Krzysztof Kapulkin and Yufeng Li

We develop a general framework for working with structured lifting problems, establishing closure and uniqueness properties of their solutions. In a subsequent paper, we apply these results to axiomatize computation rules of cubical type theory.

Keywords: lifting problems, Leibniz transpose, pushout-product, cubical type theory
