Abstract:

There are simple examples in which a variety is irreducible at a point but has a reducible tangent cone. The following theorem is proved. If ${X_p}$ is an irreducible analytic germ and if the Jacobian ideal beomes principal on the normalization then the tangent cone of $X$ at $p$ is irreducible. If, moreover, the singular set of $X$ is a manifold at $p$ then $X$ is Whitney $a,b$-regular along the singular set at $p$.
