ABSTRACT

The Padovan sequence {Pn}n≥0 is a ternary recurrent sequence defined recursively by the relation Pn = Pn–2 + Pn–3 with initials P0 = P1 = P2 = 1. In this note, we search all pairs of multiplicative dependent vectors whose coordinates are Padovan numbers. For this purpose, we apply Matveev’s theorem to find the lower bounds of the non-zero linear forms in logarithms. Techniques involving the LLL algorithm and the theory of continued fraction are utilized to reduce the bounds.
