报告摘要: We show that the irreducible desingularization of an isolated singularity given by the Grauert blow down of a negative vector bundle is unique up to isomorphism, and give a formula for the multiplicty of an isolated singularity given by the Grauert blow down of an exceptional divisor in a complex manifold. The second result can be applied to give exact formula or estimate for the multiplicity of an isolated singularity given by the Grauert blow down of a negative vector bundle. In the special case that the base is a compact Riemann surface and the line bundle is given by the divisor of a single point, this is closely related to the classical results about Weierstrass points of compact Riemann surfaces. This lecture is based on joint work with Yinji Li, Qunhuan Liu, and Xiangyu Zhou.
