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.
This result stems from a branch of pure mathematics known as Ramsey theory, which concerns the existence of highly regular patterns in any large set of randomly selected numbers, points, or objects.
