Abstract In the field of formal power series over a finite field, we prove a result which enables us to construct explicit examples of $U_{m}$ -numbers by using continued fraction expansions of algebraic formal power series of degree $m>1$ .

Let Fq be a finite field and Fq((X−1 )) the field of formal power series with coefficients in Fq. The purpose of this paper is to exhibit a family of transcendental continued fractions of formal power series over a finite field through some specific irregularities of its partial quotients

In this paper we study another form in the field of formal power series over a finite field. If the continued fraction of a formal power seriesin $\mathbb{F}_q((X^{-1}))$ begins with sufficiently largegeometric blocks, then $f$ is transcendental.

Generalized Continued Fractions

After defining a generalized C-fraction (a kind of Jacobi-Perron algorithm) for an n-tuple of formal power series over (n ≥ 2), the connection between interruptions in the algorithm and linear dependence over [x] of the power series is studied.Examples will be given showing that the algorithm behaves in a way similar to the Jacobi-Perron algorithm for an n-tuple of real numbers (the gcd-algorithm): there do exist n-tuples of formal power series f(1), f(2), …, f(n) with a C-n-fraction without interruptions but for which 1, f(1), f(2), …, f(n) is nevertheless linearly dependent over [x].Moreover an example will be given of algebraic functions f, g of degree n over [x] (formally defined) for which the C-n-fraction for f, f2, …, fn has just one interruption and that for g, g2, …, gn 1 none, while of course 1. f, f2, …, fn and 1, g, g2, …, gn admit (only) one dependence relation over [x].
