Rationals with exotic convergences. II. (English) Zbl 0776.54029
This is the continuation of an earlier paper [ibid. 39, No. 2, 141-147 (1989; Zbl 0678.54001)] investigating compatible sequential convergence structures on the group (ring) $$\mathbb{Q}$$ of rational numbers which are coarser than the usual metric convergences for $$\mathbb{Q}$$. This study includes group convergences of bounded sequences of rational numbers, unbounded group convergences in $$\mathbb{Q}$$, and ring convergences, especially in the field of algebraic numbers in connection with its transcendental extensions.
