Abstract:

It is proved that an analytic hypersurface germ $(X,0) \subseteq ({{\mathbf {C}}^{n + 1}},0)$, with nonsingular normalization, whose only singularities outside the origin are normal crossings of two n-manifolds is isomorphic to a germ of an algebraic variety at 0. As a corollary we find that weakly normal surfaces $V \subseteq {{\mathbf {C}}^3}$ with nonsingular normalization are locally algebraic.
