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 …
WebThe Brieskorn lattice H′′ of an isolated hypersurface singularity with Milnor number μ is a free C{{s}}-module of rank μ with a differential operator t=s2∂s. Based on the mixed Hodge structure on the cohomology of the Milnor fibre, M. Saito constructed C{{s}}-bases of H′′ for which the matrix of t has the form A=A0+A1s. We describe an algorithm to compute the … WebWe study the structure of the filtered Gauss-Manin system associated to a holomorphic function with an isolated singularity, and get a basis of the Brieskorn lattice Ω X, 0 n + 1 / d f ∧ d Ω X, 0 n + 1 over ℂ {{∂ t-1}} such that the action of t is expressed by
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- WebWe study the structure of the filtered Gauss-Manin system associated to a holomorphic function with an isolated singularity, and get a basis of the Brieskorn lattice over C such …
