In this work we {ital explicitly} demonstrate the equivalence of covariant (Feynman) perturbation theory with noncovariant light-front perturbation theory (LFPT) for lowest-order self-energy corrections in the (1+1)-dimensional Yukawa model. We also perform calculations in old-fashioned perturbation theory in the infinite-momentum frame (OFPT{sub {infinity}}) to elucidate the differences between LFPT and OFPT{sub {infinity}}.
