WitrynaWe generalize the notion of Thom polynomials from singularities of maps between two complex manifolds to invariant cones in representations, and collections of vector bundles. We prove that the generalized Thom polynomials, expanded in the products of Schur functions of the bundles, have nonnegative coefficients. For classical Thom … WitrynaIn Theorem 57, we show that the local invariant cycle map is an isomorphism if and only if the Betti numbers of the special ﬁber are palindromic in a suitable sense. This is a general result in that it holds for any projective morphism of smooth, complex, quasi-projective schemes. Then, in Theorem 126, we show that the local invariant cycles
