| contents | We introduce an elementary class of linearly ordered groups, called growth order groups, encompassing certain groups under composition of formal series (e.g. transseries) as well as certain groups $\mathcal{G}_{\mathcal{M}}$ of infinitely large germs at infinity of unary functions definable in an o-minimal structure $\mathcal{M}$. We study the algebraic structure of growth order groups and give methods for constructing examples. We show that if $\mathcal{M}$ expands the real ordered field and germs in $\mathcal{G}_{\mathcal{M}}$ are levelled in the sense of Marker & Miller, then $\mathcal{G}_{\mathcal{M}}$ is a growth order group. |
