요약 | A fine moduli space (see Chapter~\\ref{secn&t} Definition~\\ref{finemdli}) is constructed, for cyclic-by-$\\mathsf{p}$ covers of an affine curve over an algebraically closed field $k$ of characteristic $\\mathsf{p}>0$. An intersection (see Definition~\\ref{M}) of finitely many fine moduli spaces for cyclic-by-$\\mathsf{p}$ covers of affine curves gives a moduli space for $\\mathsf{p}'$-by-$\\mathsf{p}$ covers of an affine curve. A local moduli space is also constructed, for cyclic-by-$\\mathsf{p}$ covers of $Spec(k((x)))$, which is the same as the global moduli space for cyclic-by-$\\mathsf{p}$ covers of $\\mathbb{P}. |
요약 | 1-\\{0\\}$ tamely ramified over $\\infty$ with the same Galois group. Then it is shown that a restriction morphism (see Lemma~\\ref{res mor-2}) is finite with degrees on connected components $\extsf{p}$ powers: There are finitely many deleted points (see Figure 1) of an affine curve from its smooth completion. A cyclic-by-$\\mathsf{p}$ cover of an affine curve gives a product of local covers with the same Galois group, of the punctured infinitesimal neighbourhoods of the deleted points. So there is a restriction morphism from the global moduli space to a product of local moduli spaces. |
