coq-paradoxes

Paradoxes in Set Theory and Type Theory. A formalisation of Burali-Forti paradox in system U (the existence of an ordinal of ordinals is inconsistent), of Diaconescu paradox (axiom of choice implies excluded-middle), of Reynolds paradox (there is no set-theoretic model of system F) and Hurkens paradox in system U (adapted by H. Geuvers to show the inconsistency of Excluded-Middle in impredicative-Set Calculus of Inductive Constructions).
