On Bergman's Diamond Lemma for Ring Theory
This expository paper deals with the Diamond Lemma for ring theory, which is proved in the first section of G.M. Bergman, The Diamond Lemma for Ring Theory, Advances in Mathematics, 29 (1978), pp. 178–218. No originality of the present note is claimed on the part of the author, except for some suggestions and figures. Throughout this paper, I shall mostly use Bergman's expressions in his paper.
