全是复曲面左心室造影-奇点允许射影可解

All toric l.c.i.-singularities admit projective crepant resolutions

Dimitrios I. Dais, Christian Haase, G"unter M. Ziegler

摘要:

众所周知,所有可嵌入仿射空间中的超曲面的完全相交的阿贝尔商奇点的底层空间都可以通过所有维度上的射影环面等变的可折双有理态射来整体求解。在本文中,我们将这一结果推广到整个复曲面l.c.i.-奇点我们的证明利用中岛的分类定理和一些特殊的技术,从复曲面和离散几何。

英文摘要:

It is known that the underlying spaces of all abelian quotient singularities which are embeddable as complete intersections of hypersurfaces in an affine space can be overall resolved by means of projective torus-equivariant crepant birational morphisms in all dimensions. In the present paper we extend this result to the entire class of toric l.c.i.-singularities. Our proof makes use of Nakajima's classification theorem and of some special techniques from toric and discrete geometry.
