چکیده
We show that the modular decomposition of a countable graph can be defined from this graph, given with an enumeration of its set of vertices, by formulas of Monadic Second-Order logic. A second main result is the definition of a representation of modular decompositions by a low degree relational structures, also constructible by Monadic Second-

The modular decomposition of countable graphs. Definition and construction in monadic second-order logic
We consider the notion of modular decomposition for countable graphs. The modular decomposition of a graph given with an enumeration of its set of vertices can be defined by formulas of monadic second-order logic. Another result is the definition of a representation of modular decompositions by low degree relational structures. Such relational structures can also be defined in the considered gr...
متن کاملGraph equivalences and decompositions definable in Monadic Second-Order Logic. The case of Circle Graphs
Many graph properties and graph transformations can be formalized inMonadic Second-Order logic. This language is the extension of First-Order logic allowing variables denoting sets of elements. In the case of graphs, these elements can be vertices, and in some cases edges. Monadic second-order graph properties can be checked in linear time on the class of graphs of tree-width at most k for any ...
متن کاملThe monadic second-order logic of graphs XVI : Canonical graph decompositions
This article establishes that the split decomposition of graphs introduced by Cunnigham, is definable in Monadic Second-Order Logic.This result is actually an instance of a more general result covering canonical graph decompositions like the modular decomposition and the Tutte decomposition of 2-connected graphs into 3-connected components. As an application, we prove that the set of graphs hav...
متن کاملRegularity Equals Monadic Second-Order Definability for Quasi-trees
Quasi-trees generalize trees in that the unique "path" between two nodes may be infinite and have any finite or countable order type, in particular that of rational numbers. They are used to define the rank-width of a countable graph in such a way that it is the least upper-bound of the rankwidths of its finite induced subgraphs. Join-trees are the corresponding directed trees and they are also...
متن کاملA Hierarchical Approach to Graph Automata and Monadic Second-Order Logic over Graphs
A hierarchical approach to the decomposition of graphs is introduced which is related to the notion of tree decomposition. On this basis a hierarchical automaton model for graphs is deened. We show that this automaton model is (relative to an appropriate class of graphs) equivalent to monadic second-order logic in expressive power, properly strengthening previous results on monadic second-order...
