D.6.13 mondromy_lib

Library:
mondromy.lib
Purpose:
Monodromy of an Isolated Hypersurface Singularity
Author:
Mathias Schulze, email: mschulze@mathematik.uni-kl.de

Overview:
A library to compute the monodromy of an isolated hypersurface singularity. It uses an algorithm by Brieskorn (manuscripta math. 2 (1970), 103-161) to compute a connection matrix of the meromorphic Gauss-Manin connection up to arbitrarily high order, and an algorithm of Gerard and Levelt (Ann. Inst. Fourier, Grenoble 23,1 (1973), pp. 157-195) to transform it to a simple pole.

Procedures:

D.6.13.1 detadj  determinant and adjoint matrix of square matrix U
D.6.13.2 invunit  series inverse of polynomial u up to order n
D.6.13.3 jacoblift  lifts f^kappa in jacob(f) with minimal kappa
D.6.13.4 monodromyB  monodromy of isolated hypersurface singularity f
D.6.13.5 H2basis  basis of Brieskorn lattice H"
