Normal two-dimensional singularities
WebIt is clear that maximally elliptic singularities should play an important role in the theory of normal two-dimensional singularities, especially from the point of view of classification of normal two-dimensional singularities. Our main results are the following. Theorem A. Let ti: M —> F be a resolution of a normal two-dimensional WebIn this chapter we consider normal singularities of two-dimensional varieties over \(\mathbb{C}\). A two-dimensional integral algebraic variety is called a surface. A normal singularity on a surface is an isolated singularity and by Corollary 3.5.17 it is a Cohen–Macauley singularity.
