= Coleman power series for a CM formal group
{c}
{title2=$f_u(t_n)=u_n$}
For a height-one <CM elliptic curve> formal group and compatible $\mathfrak p^n$-division parameters $t_n$, an integral Coleman series interpolates a norm-compatible sequence of local units $u_n$. Its norm relation is multiplication of its translates by the $\mathfrak p$-torsion, with coefficient Frobenius where required by the unramified base. <Coates–Wiles homomorphisms> and the <Frobenius-corrected logarithm> turn this local series into critical values and measures.
