Abstract
The main goal of this chapter is to show that every reduced complex space X has, up to a canonical isomorphism, a normalization \(\hat X\). This space \(\hat X\)will turn out to be a one-sheeted analytic covering of X. For this reason we first develop a general theory of such coverings and prove a Local Existence Theorem. This theorem easily implies OKA’s theorem that the normalization sheaf \({{\hat{\mathcal{O}}}_{X}}\) of the structure sheaf \({{\mathcal{O}}_{X}}\) is \({{\mathcal{O}}_{X}}\)-coherent.
