Erik Palmgren: From type theory to setoids and back
The lecture was held within the framework of the Hausdorff Trimester Program: Types, Sets and Constructions. Abstract: Errett Bishop proposed several type-theoretic languages to be used for formalization of constructive mathematics. The notion of set of (Bishop-Bridges 1985) always requi

Fabio Pasquali: Assemblies as an elementary quotient completion
The lecture was held within the framework of the Hausdorff Trimester Program: Types, Sets and Constructions. Abstarct: We characterize the category of assemblies as an elementary quotient completion, a construction introduced by Maietti and Rosolini to axiomatize the category of setoids u

Jacopo Emmenegger: W types in the setoid model
The lecture was held within the framework of the Hausdorff Trimester Program: Types, Sets and Constructions. Abstact: Current arguments to obtain initial algebras for polynomial endofunctors in categories of equivalence relations rely on assumptions like UIP or on constructions that invol
