Let the trunk of a graph G be the graph obtained by removing all leaves of G. We prove that, for every integer c \_> 2, there are at most finitely many trunks of serniharrnonic graphs with cyclomatic number e--in contrast to the fact established by the last two of the present authors in their paper

β¦ Synopsis
For a given planar graph G with a set A of independent vertices, we provide a best-possible upper bound for the minimum cyclomatic number of connected induced subgraphs of G containing A. The extremal graphs are also characterized. @

The problem of determining the domination number of a graph is a well known NPhard problem, even when restricted to planar graphs. By adding a further restriction on the diameter of the graph, we prove that planar graphs with diameter two and three have bounded domination numbers. This implies that
We give an upper bound for w(A), the minimum cyclomatic number of connected induced subgraphs containing a given independent set A of vertices in a given graph G. We also give an upper bound for w(A) when G is triangle-free. We show that these two bounds are best possible. Similar results are obtai
The concept of the star chromatic number of a graph was introduced by Vince (A. Vince, Star chromatic number, J. Graph Theory 12 (1988), 551--559), which is a natural generalization of the chromatic number of a graph. This paper calculates the star chromatic numbers of three infinite families of pla
## This note generalizes the notion of cyclomatic number (or cycle rank) from Graph Theory to Hypergraph Theory and links it up with the concept of planarity in hypergraphs which was recently introducea by R.P. Jones. Sharp bounds are obtained for the cyclomatic number of the planar hypergraphs an
