Özet

In this paper, we give all solutions of the Diophantine equation Tn = RkRm, where

(n; k;m) 2 Z+ x Z+ x Z+, Rk is the Perrin sequence, and Tn is the Tribonacci sequence.

We show that this Diophantine equation has only 7 integer solution triples. For the

proof, we use Baker's method. Our motivation is to show that linear forms in logarithms

can still be e ectively used for the solutions of di erent Diophantine equations involving

beside classical number sequences such as Fibonacci or Lucas sequences.
