Issues concerning loop skeleton diagrams, renormalization in the massive case, and the usage of the DSE for vertices involving matrix strucures are investigated.

Abstract

We discuss the implementation of the dressed skeleton expansion (DSE) and analyze various features of this perturbative calculational method in simple field-theory models in 1+1 dimensions. In particular, we investigate issues concerning loop skeleton diagrams, renormalization in the massive case, and the usage of the DSE for vertices involving matrix strucures.
