Abstract
Taking sigma-exchange Fock term of nucleon self-energy in nuclear matt er as an example, we renormalized the nucleon self-energy by both dime nsional regularization method and dispersion relation method in the Wa lecka model. We compared them numerically and found them identical, in dependent of the renormalization methods.
