Locally bounded enriched categories
Rory B. B. Lucyshyn-Wright, Jason Parker
We define and study the notion of a locally bounded enriched category over a (locally bounded) symmetric monoidal closed category, generalizing the locally bounded ordinary categor…
Inner automorphisms of presheaves of groups
Jason Parker
It has been proven by Schupp and Bergman that the inner automorphisms of groups can be characterized purely categorically as those group automorphisms that can be coherently extend…
Covariant Isotropy of Grothendieck Toposes
Jason Parker
We provide an explicit characterization of the covariant isotropy group of any Grothendieck topos, i.e. the group of (extended) inner automorphisms of any sheaf over a small site.…
Polymorphic Automorphisms and the Picard Group
Pieter Hofstra, Jason Parker, Philip J. Scott
We investigate the concept of definable, or inner, automorphism in the logical setting of partial Horn theories. The central technical result extends a syntactical characterization…
