Abstract:
In this paper it is shown how non-pointed exactness provides a
framework which allows a simple categorical treatment of the basics
of Kurosh--Amitsur radical theory in the non-pointed case. This is
made possible by a new approach to semi-exactness, in the sense of
the first author, using adjoint functors. This framework also reveals
how categorical closure operators arise as radical theories.
