Bipartite Density of Generalized Petersen Graphs
… density of several classes of Generalized Petersen Graphs. These graphs are denoted by P(n, k), where n ≥ 3 and 1 ≤ k < n with n ≠ 2k. The Generalized Petersen Graph P(n, k) has vertices [special characters omitted] and edges [special characters omitted] where subscript addition is modulo …

Excluding Two Minors of the Petersen Graph
… we begin with a brief survey of the Petersen graph and its role in graph theory. We will then develop an alternative decomposition to clique sums for 3-connected graphs, called T-sums. This decomposition will be used in Chapter 2 to completely characterize those graphs which have no …

Edge-colorings and flows in Class 2 graphs
… Conjecture, the Berge-Fulkerson Conjecture, the Petersen Coloring Conjecture and the Tutte's 5-flow Conjecture. We obtain some new restrictions on the structure of a possible minimum counterexample to the former two conjectures. We prove that the Petersen graph is, in a specific sense, the only …

Clear Air Turbulence analysis using isentropic methods.
… analyses were completed subjectively and by the Petersen (1986) objective analysis scheme for a 24-h Clear Air Turbulence (CAT) outbreak over the midwest United States. The purpose of the study is to determine if areas of high CAT potential could be identified by subjective isentropic analyses, …
