Combinatorial problems on series-parallel graphs,These include (i) the decision problem, and (ii) the minimum edge (vertex) deletion problem both with respect to a property characterized by a finite number of forbidden graphs, and (iii) the generalized matching problem.

Characterization of polyhex graphs as applied to chemistry,s for characterizing the polyhex graphs are described and discussed, including the topological index, characteristic polynomial, sextet polvnomial, etc. Enumeration of the number of the maximum matching (or Kekulé patterns) is also discussed.

Minimally Invasive Total Joint Arthroplastyhe vertices classified according to the distance from a given vertex. Some fundamental properties of the centrality functions and the set of central vertices are summarized. Inserting an edge between a center and a vertex, the stability of the set of central vertices are investigated..For a weakly c

https://doi.org/10.1007/978-1-4939-1317-6. We examine the structures of symmetric submodular systems and provide a decomposition theory of symmetric submodular systems. The theory is a generalization of the decomposition theory of 2-connected graphs developed by W. T. Tutte.
