D.6.11 mondromy_lib

Monodromy of an Isolated Hypersurface Singularity
Mathias Schulze, email: mschulze@mathematik.uni-kl.de

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.
