Some remarks on formal power series and formal Laurent series

Mathematica Slovaca, 2017
Abstract In this article we consider the topology on the set of formal Laurent series induced by the ultrametric defined via the order. In particular, we establish that the product of formal Laurent series, considered in [GAN, X. X.—BUGAJEWSKI, D.:On formal Laurent series, Bull. Braz. Math. Soc. 42 (2011), 415–437], is not continuous. We
