On Curves on Sandwiched Surface Singularities
Fixed a point O on a non-singular surface S and a complete mO-primary ideal I in OS,O , the curves on the surface X = BlI (S) obtained by blowing-up I are studied in terms of the base points of I. Criteria for the principality of these curves are obtained. New formulas for their multiplicity, intersection numbers and order of singularity at the singularities of X are given. The semigroup of bra...
متن کاملOn −k for Normal Surface Singularities
In this paper we show the lower bound of the set of non-zero−K for normal surface singularities establishing that this set has no accumulation points from above. We also prove that every accumulation point from below is a rational number and every positive integer is an accumulation point. Every rational number can be an accumulation point modulo Z. We determine all accumulation points in [0, 1...
متن کاملThe Nash Problem on Arcs for Surface Singularities
1 Let (X,O) be a germ of a normal surface singularity, π : X̃ −→ X be the minimal resolution of singularities and let A = (ai,j) be the n × n symmetrical intersection matrix of the exceptional set of X̃. In an old preprint Nash proves that the set of arcs on a surface singularity is a scheme H, and defines a map N from the set of irreducible components of H to the set of exceptional components of...
متن کاملSurface singularities in nematics and some notes on cholesterics
2014 A topological analysis of surface and bulk configurations in cholesterics and nematics is given. Volovik’s procedure for combining surface and bulk defects is reviewed and illustrated, and the problem of twist in cholesterics is discussed from the point of view of Cladis et al. These considerations are applied to cholesteric boojums. Also, the question of non-singular textures is studied a...
