발표 제목 및 초록

제목: Links and Milnor fibers of isolated singular points of complete intersections 

초록: Links of isolated singular points of complete intersections provide many interesting examples in low dimensional topology. And studying Milnor fibers of isolated singular points of complete intersections is a classical topic in singularity theory. In the first part of this talk, I will give a brief review of the theory of isolated singular points of complete intersections. Then I will discuss how certain topological invariants of links of isolated complete intersection singularities are related to their Milnor fibers. The last part of this talk is based on joint works (some in progress) with Anatoly Libgober and Nikolai Saveliev.

제목: Positivity of the tangent bundle of projective manifolds 

초록: After giving a solution to Hartshorne’s conjecture by Mori, the study of projective manifolds whose tangent bundles admit some positivity properties has attracted a lot of attention and such properties are usually expected to impose strong restrictions on the geometry of the underlying projective manifolds. In this talk, I will present some restrictions on the underlying projective manifolds imposed by bigness of the tangent bundle. Some related questions will be also discussed.

제목: Symmetrizer group of a projective hypersurface  

초록: To each projective hypersurface which is not a cone, we associate an abelian linear algebraic group called the symmetrizer group of the corresponding symmetric form. This group describes the set of homogeneous polynomials with the same Jacobian ideal and gives a conceptual explanation of results by Ueda-Yoshinaga and Wang. In particular, the diagonalizable part of the symmetrizer group detects Sebastiani-Thom property of the hypersurface and its unipotent part  is related to the singularity of the hypersurface.
