On the (s, t)-Pell and (s, t)-Pell-Lucas sequences and their matrix representations

In this paper, we first give new generalizations for (s, t)-Pell {p(n)(s, t)}(n is an element of N) and (s, t)-Pell Lucas {q(n)(s, t)}(n is an element of N) sequences for Pell and Pell-Lucas numbers. Considering these sequences, we define the matrix sequences which have elements of {p(n)(s, t)}(n is an element of N) and {q(n)(s, t)}(n is an element of N). Then we investigate their properties.
