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.Keywords
