Equisingular Deformations of Plane Curve and of Sandwiched Singularities
Let C be an isolated plane curve singularity, and (C, l) be a decorated curve. In this article we compare the equisingular deformations of C and the sandwiched singularity X(C, l). We will prove that for l ≫ 0 the functor of equisingular deformations of C and (C, l) are equivalent. From this we deduce a proof of a formula for the dimension of the equisingular stratum. Furthermore we will show h...
متن کاملOn the Freeness of Equisingular Deformations of Plane Curve Singularities
We consider surface singularities in C3 arising as the total space of an equisingular deformation of an isolated curve singularity of the form f(x, y)+zg(x, y) with f and g weighted homogeneous. We give a criterion that such a surface is a free divisor in the sense of Saito. We deduce that the Hessian deformation defines a free divisor for nonsimple weighted homogeneous singularities, and that ...
متن کاملInfinitesimal Deformations and Obstructions for Toric Singularities
The obstruction space T 2 and the cup product T 1×T 1 → T 2 are computed for toric singularities.
متن کاملDeformations of Symplectic Cohomology and Ade Singularities
Let X be the plumbing of copies of the cotangent bundle of a 2−sphere as prescribed by an ADE Dynkin diagram. We prove that the only exact Lagrangian submanifolds in X are spheres. Our approach involves studying X as an ALE hyperkähler manifold and observing that the symplectic cohomology of X will vanish if we deform the exact symplectic form to a generic non-exact one. We will construct the s...
متن کاملDeformations of Polynomials, Boundary Singularities and Monodromy
We study the topology of polynomial functions by deforming them generically. We explain how the non-conservation of the total “quantity” of singularity in the neighbourhood of infinity is related to the variation of topology in certain families of boundary singularities along the hyperplane at infinity. 2000 Math. Subj. Class. 32S30, 14D05, 32S40, 58K60, 14B07, 58K10, 55R55.
