On Degree Sequences of Graphs with Given Cyclomatic Number


Manfred Schocker


Starting with the Criterion by Gutman and Ruch for graphical partitions, Gutman analyzed degree sequences of connected graphs with cyclomatic number $c$, for $c\le 5$. In this paper, his results are revisited and, based on the Erdös-Gallai Criterion, extended to arbitrary values of $c$. Necessary and sufficient conditions are obtained for any partition to be the degree sequence of a connected graph with cyclomatic number $c$.
