Polynomial functors and W-types for groupoids

This thesis contributes to the semantics of Martin-Lof type theory and the theory of polynomial functors. We do so by investigating polynomial functors on the category of groupoids and their initial algebras, known as W-types. We consider several versions of polynomial functors: both simple and depe...
