WebIN NORMAL TWO-DIMENSIONAL SINGULARITIES TOMOHIRO OKUMA , MARIA EVELINA ROSSI , KEI-ICHI WATANABE and KEN-ICHI YOSHIDA Abstract. Let (A,m) be an excellent two-dimensional normal local domain. In this paper, we study the elliptic and the strongly elliptic ideals of A with the aim to characterize elliptic and strongly elliptic … 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
