This volume contains the proceedings of a conference held in July, 2007 at
the University of Minnesota, Duluth, in honor of Joseph A. Gallian's 65th
birthday and the 30th anniversary of the Duluth Research Experience for
Undergraduates.

In keeping with Gallian's extraordinary expository ability and broad
mathematical interests, the articles in this volume span a wide variety of
mathematical topics, including algebraic topology, combinatorics, design
theory, forcing, game theory, geometry, graph theory, group theory,
optimization, and probability.

Some of the papers are purely expository while others are research
articles. The papers are intended to be accessible to a general
mathematics audience, including first-year or second-year graduate
students. This volume should be especially useful for mathematicians
seeking a new research area, as well as those looking to enrich
themselves and their research programs by learning about problems and
techniques used in other areas of mathematics.
