We show how methods of continuum perturbation theory can be used to simplify perturbative lattice calculalions. We use the technique of asymptotic expansions to expand lattice loop integrals around the continuum limit. After the expansion, all nontrivial dependence on momenta and masses is encoded i

We extend chiral perturbation theory to include linear dependence on the lattice spacing a for the Wilson action. The perturbation theory is written as a double expansion in the small quark mass m4 and lattice spacing a. We present formulae for the mass and decay constant of a flavor-non-singlet mes
## Abstract An adiabatic formula for the contracted Hamiltonian in a reference space containing boundβstate eigenfunctions of degenerate energy levels embedded in the continuum is derived. A general factorization theorem for the dynamic operator__S__~Ξ±~(0, β β/Ξ») is proved, and the cancellation of
