Idea

A dual adjunction between categories CC and DD is an adjunction between the opposite category C opC^{op} of CC and DD.

The concept arises in the context of duality.

Dual adjunctions between concrete categories may be represented by dualizing objects.

Dual adjunctions between posets are also called Galois connections.
