Abstract

The Tribonacci sequence T := {Tn}n≥0 has initial values T0 = T1 =0, T2 =1 and each term afterwards is the sum of the preceding three terms. In this paper, we study the equation Tn = kTm, where k is an S-unit, for a finite set S of primes. In particular, we show that any two members of the diophantine triple {9, 56, 103} associated to T +1, can not be extended to other diophantine triple associated to T +1.
