Abstract

This article explains a detailed example of the general result developed in the first part [3]. We were motivated by [1], where S. Barannikov describes a Frobenius structure attached to the Laurent polynomial f(u 0,..., u n ) = u 0 +...+ u n restricted to the torus U = {(u 0,..., u n ) ∈ ℂn+1 | Π i u i = 1} and shows that it is isomorphic to the Frobenius structure attached to the quantum cohomology of the projective space ℙn(ℂ) (as defined e.g., in [5]).KeywordsHodge StructureJordan BlockQuantum CohomologyNewton PolyhedronMixed Hodge StructureThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
