Web18 de mar. de 2014 · We study the integrable variation of twistor structure associated to any solution of the Toda lattice with opposite sign. In particular, we give a criterion when it has an integral structure. It follows from two results. One is the explicit computation of the Stokes factors of a certain type of meromorphic flat bundles. The other is an explicit … WebKeywords: Linear free divisors, prehomogenous vector spaces, quiver representations, Gauß-Manin-system, Brieskorn lattice, Birkhoff problem, spectral numbers, Frobenius manifolds. 1 Introduction In this paper we study Frobenius manifolds arising as deformation spaces of linear functions on certain non-isolated singularities, the so-called linear free …

WebThe Brieskorn lattice of an isolated hypersurface singularity gives rise to an invariant of the right equivalence class of the singularity. It is finer than the mixed Hodge structure of the singularity, and it is a good candidate for Torelli type questions. Webstructure of the Brieskorn lattice and the Fourier-Laplace transform [Sch00, SS01]. We use standard basis methods, univariate factoriza-tion, and a normal form algorithm for the microlocal structure of the Brieskorn lattice, the latter of which is not published yet. These meth-ods lead to algorithms [Sch02, Sch01a, Sch01b] to compute Hodge-
