Two applications of van der Waerden's theorem and some related questions
Sukumar Das Adhikari
Harish-Chandra Research Institute.
We start with the statements of some early Ramsey-type theorems. We then derive one of them from a version of Ramsey's theorem and observe that a generalization follows from van der Waerden's theorem. After discussing some related results, we move to a more recent application of van der Waerden's theorem.
