摘要:
Special kinds of continued fractions have been proved to converge to transcendental real numbers by means of the celebrated Subspace Theorem. In this paper we study the analogous p-adic problem. More specifically, we deal with Browkin p-adic continued fractions. First we give some new remarks about the Browkin algorithm in terms of a p-adic Euclidean algorithm. Then, we focus on the heights of some p-adic numbers having a periodic p-adic continued fraction expansion and we obtain some upper bounds. Finally, we exploit these results, together with p-adic Roth-like results, in order to prove the transcendence of three families of p-adic continued fractions.
