Abstract

Given a monodromy representation ρ\rho of the projective line minus mm points, one can extend the resulting vector bundle with connection map canonically to a vector bundle with logarithmic connection map over all of the projective line. Now, since vector bundles split as twisting sheaves over the projective line, the focus of this work regards knowing the exact decomposition; i.e. computing the roots. Particularly, we compute the roots for all finite-dimensional ρ\rho when m=2m = 2 and for all ρ\rho of dimension less than 33 when m=3m = 3.
