WebThe theory of normal surface singularities is a distinguished part of analytic or algebraic geometry with several important results, its own technical machinery, and several open problems. Recently several connections were established with low dimensional topology, symplectic geometry and theory of Stein fillings.

Webdimensional regular local rings to two-dimensional normal local rings S having a rational singularity. The principal result in part II is to the effect that any product of complete ideals in such an S is again complete (cf. Theorem (7. i)). This implies, among other things, that rational singularities can be resolved by quadratic ...
