abstract = {It appears that large scale calculations in particle physics
often require to solve systems of linear equations with rational number
coefficients exactly. If classical Gaussian elimination is applied to a
\emph{dense} system, the time needed to solve such a system grows exponentially
in the size of the system. In this tutorial paper, we present a standard
technique from computer algebra that avoids this exponential growth:
homomorphic images. Using this technique, big dense linear systems
can be solved in a much more reasonable time than using Gaussian
elimination over the rationals.},
