Libra: a package for transformation of differential systems for multiloop integrals
We present a new package for Mathematica system, called Libra. Its purpose is to provide convenient tools for the transformation of the first-order differential systems $partial_i boldsymbol j = M_i boldsymbol j$ for one or several variables...
In particular, Libra is designed for the reduction to $epsilon$-form of the differential systems which appear in multiloop calculations. The package also contains some tools for the construction of general solution: both via perturbative expansion of path-ordered exponent and via generalized power series expansion near regular singular points.Libra also has tools to determine the minimal list of coefficients in
