Abstract: Paul Gunnells has developed an algorithm for computing actions of Hecke operators on arithmetic cohomology below the cohomological dimension. His algorithm uses a conjecture concerning LLL-reduced matrices. We prove this conjecture in dimensions two through five and disprove it in all higher dimensions.
GP Code for the dimension five case.
GP Code for Gram-Schmidt reduction and testing LLL conditions.
