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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
