摘要：

In this work we 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-infinity) to elucidate the differences between LFPT and OFPT-infinity.
