Definition:Ordered Group Automorphism

Definition
Let $\struct {G, \circ, \preceq}$ be an ordered group.

An ordered group automorphism from $\struct {G, \circ, \preceq}$ to itself is a mapping $\phi: G \to G$ that is both:


 * $(1): \quad$ A group automorphism, that is, a group isomorphism from the group $\struct {G, \circ}$ to itself


 * $(2): \quad$ An order isomorphism from the ordered set $\struct {G, \preceq}$ to itself.
