  1. 11. A Proof and Formalization of the Initiality Conjecture of Dependent Type Theory

    Author : Menno de Boer; Peter LeFanu Lumsdaine; Alexander Berglund; Bas Spitters; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dependent type theory; Category theory; Contextual categories; Initiality; Formalization; Mathematics; matematik; matematisk logik; Mathematical Logic;

    Abstract : In this licentiate thesis we present a proof of the initiality conjecture for Martin-Löf’s type theory with 0, 1, N, A+B, ∏AB, ∑AB, IdA(u,v), countable hierarchy of universes (Ui)iєN closed under these type constructors and with type of elements (ELi(a))iєN. We employ the categorical semantics of contextual categories. READ MORE

  3. 13. Ultrasheaves

    Author : Jonas Eliasson; Viggo Stoltenberg-Hansen; Steve Awodey; Carsten Butz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Logic; symbolic and mathematical; 03G30; 03C20; 03H05; Matematisk logik; Mathematical logic; Matematisk logik;

    Abstract : This thesis treats ultrasheaves, sheaves on the category of ultrafilters. In the classical theory of ultrapowers, you start with an ultrafilter and, given a structure, you construct the ultrapower of the structure over the ultrafilter. READ MORE
