Thomas W Tucker Editor

Lowell W. Beineke is Schrey Professor of Mathematics at Indiana University–Purdue University Fort Wayne, where he has been since receiving his Ph.D. from the University of Michigan under the guidance of Frank Harary. His graph theory interests are broad, and include topological graph theory, line graphs, tournaments, decompositions and vulnerability. With Robin Wilson he edited Selected Topics in Graph Theory (3 volumes), Applications of Graph Theory, Graph Connections and Topics in Algebraic Graph Theory. Until recently he was editor of the College Mathematics Journal. Robin J. Wilson is Professor of Pure Mathematics at the Open University, UK, and Emeritus Professor of Geometry at Gresham College, London. After graduating from Oxford, he received his Ph.D. in number theory from the University of Pennsylvania. He has written and edited many books on graph theory and the history of mathematics, including Introduction to Graph Theory and Four Colours Suffice, and his research interests include graph colourings and the history of combinatorics, and he has Erdős number 1. He has won a Lester Ford Award and a George Pólya Award from the MAA for his expository writing. Jonathan L. Gross is Professor of Computer Science at Columbia University. His mathematical work in topology and graph theory have earned him an Alfred P. Sloan Fellowship, an IBM Postdoctoral Fellowship, and numerous research grants. With Thomas Tucker, he wrote Topological Graph Theory and several fundamental pioneering papers on voltage graphs and on enumerative methods. He has written and edited eight books on graph theory and combinatorics, seven books on computer programming topics, and one book on cultural sociometry. Thomas W. Tucker is the Charles Hetherington Professor of Mathematics at Colgate University, where he has been since 1973, after a PhD in 3-manifolds from Dartmouth in 1971 and a postdoc at Princeton (where his father A. W. Tucker was chairman and John Nash's thesis advisor). He is co-author (with Jonathan Gross) of Topological Graph Theory. His early publications were on non-compact 3-manifolds, then topological graph theory, but his recent work is mostly algebraic, especially distinguishability and the group-theoretic structure of symmetric maps.
