Exploring a variety of topics from the field of Ramsey theory within the set of integers, Landman and Robertson introduce students to mathematical research, giving them an appreciation for the essence of mathematical research and getting them started on their own research work among the unsolved problems in the flourishing area of Ramsey theory on the integers. They also provide a resource for all mathematicians who are interested in combinatorial or number theory problems, particularly Erdös-type problems. The second edition moves some problems from unsolved to solved, updates other matters, and adds some new sections. Annotation ©2015 Ringgold, Inc., Portland, OR (protoview.com)
