Geometry of nondegenerate polynomials: Motivic nearby cycles and Cohomology of contact loci
Geometry of nondegenerate polynomials: Motivic nearby cycles and Cohomology of contact loci
We study polynomials with complex coefficients which are nondegenerate in two senses, one of Kouchnirenko and the other with respect to its Newton polyhedron, through data on contact loci and motivic nearby cycles. Introducing an explicit description of these quantities we can answer in part the question concerning the motivic …
