blog.fefe.de/?ts=9afe5ac7: Warum kann in Grünwald keine 30-Zone eingeführt werden?Na ist doch klar!

"Die Leute fahren in den 30er-Zonen eh 50", will er festgestellt haben. Und er weiß auch warum: In Grünwald hätten viele Leute große Autos. Wenn man da aufs Gas tre...

Formalising Yoneda Ext in Univalent Foundations

Ext groups are fundamental objects from homological algebra which underlie important computations in homotopy theory. We formalise the theory of Yoneda Ext groups in homotopy type theory (HoTT) using the Coq-HoTT library. This is a constructive approach to Ext which does not require projective or injective resolutions. Using univalence, we show how these Ext groups can be naturally represented in HoTT. We give a novel proof and formalisation of the usual six-term exact sequence via a fibre sequence of 1-types (or groupoids), along with an application. In addition, we discuss our formalisation of the contravariant long exact sequence of Ext, an important computational tool. Along the way we implement and explain the Baer sum of extensions and how Ext is a bifunctor.
