A note on the Littlewood conjecture in positive characteristic
Abstract
The main purpose of this note is to construct families of pairs of formal power series over a finite field, which satisfy the appropriate analogue of Littlewood's conjecture in Diophantine approximation. On the way, the continued fraction expansion, with linear pattern, of a family of formal power series is given.
