Thom Series of Contact Singularities

چکیده

Thom polynomials measure how global topology forces singularities. The power of Thom polynomials predestine them to be a useful tool not only in differential topology, but also in algebraic geometry (enumerative geometry, moduli spaces) and algebraic combinatorics. The main obstacle of their widespread application is that only a few, sporadic Thom polynomials have been known explicitly. In this paper we develop a general method for calculating Thom polynomials of singularities. Along the way, relations with the equivariant geometry of (punctual, local) Hilbert schemes, and with iterated residue identities are revealed.

On the Structure of Thom Polynomials of Singularities

Thom polynomials of singularities express the cohomology classes dual to singularity submanifolds. A stabilization property of Thom polynomials is known classically, namely that trivial unfolding does not change the Thom polynomial. In this paper we show that this is a special case of a product rule. The product rule enables us to calculate the Thom polynomials of singularities if we know the T...

9 M ay 2 00 7 Thom polynomials and Schur functions : the singularities I 2 , 2 ( − )

The global behavior of singularities is governed by their Thom polynomials (cf. [35], [14], [1], [11], [31]). Knowing the Thom polynomial of a singularity η, denoted T η, one can compute the cohomology class represented by the η-points of a map. We do not attempt here to survey all activities related to computations of Thom polynomials, which are difficult tasks in general. In the present paper...

Positivity of Legendrian Thom polynomials

We study Legendrian singularities arising in complex contact geometry. We define a one-parameter family of bases in the ring of Legendrian characteristic classes such that any Legendrian Thom polynomial has nonnegative coefficients when expanded in these bases. The method uses a suitable Lagrange Grassmann bundle on the product of projective spaces. This is an extension of a nonnegativity resul...

6 S ep 2 00 9 Positivity of Thom polynomials II : the Lagrange singularities

We study Thom polynomials associated with Lagrange singularities. We expand them in the basis of Q̃-functions. This basis plays a key role in the Schubert calculus of isotropic Grassmannians. We prove that the Q̃-function expansions of Thom polynomials of Lagrange singularities have always nonnegative coefficients. This is an analog of a result on Thom polynomials of mapping singularities and Sch...

Spectral Pairs, Mixed Hodge Modules, and Series of Plane Curve Singularities

We consider a mixed Hodge module M on a normal surface sin-gularity (XXx) and a holomorphic function germ f : (XXx) ! (C 0). For the case that M has an abelian local monodromy g r o u p , w e g i v e a formula for the spectral pairs of f with values in M. This result is applied to generalize the Sebastiani-Thom formula and to describe the behaviour of spectral pairs in series of singularities.
