Regular Expressions for Tree-Width 2 Graphs

pdf-format:
LIPIcs-ICALP-2022-121.pdf (0.8 MB)

Abstract

We propose a syntax of regular expressions, which describes languages of tree-width 2 graphs. We show that these languages correspond exactly to those languages of tree-width 2 graphs, definable in the counting monadic second-order logic (CMSO).
