ARITHMETICS OF SOME SEQUENCES VIA 2 -DETERMINANTS
. We extend our investigation of 2-determinants, which we defined in a previous paper. For a linear homogenous recurrence of the second order, we consider relations between different sequences satisfying the same linear homogeneous recurrence of the second order. After we prove a generalized identity of d’Ocagne, we derive, from a single identity, a number of classical identities (and their generalizations) such as d’Ocagne’s, Cassini’s, Catalan’s
