Accessible set endofunctors are universal
Libor Barto

TL;DR
The paper demonstrates that any concretizable category can be fully embedded into the category of accessible set functors, establishing a universal property for accessible set endofunctors.
Contribution
It introduces the universality of accessible set endofunctors by showing their capacity to embed any concretizable category fully.
Findings
Every concretizable category can be fully embedded into accessible set functors.
Accessible set endofunctors are universal for concretizable categories.
The result bridges category theory and accessible functor theory.
Abstract
It is shown that every concretizable category can be fully embedded into the category of accessible set functors and natural transformations.
