Abstract
We demonstrate that a direct approach to improving Hamiltonian lattice gaug e theory is possible, Our approach is to correct errors in the Kogut-Susski nd Hamiltonian by incorporating additional gauge invariant terms. The coeff icients of these terms are chosen so that the order a(2) classical errors v anish. We conclude with a brief discussion of tadpole improvement in Hamilt onian lattice gauge theory.
