Relationships between pell and pell-lucas polynomials and extended hecke groups
Özet
In this paper, we consider Pell and Pell-Lucas polynomials. Using the roots of these polynomials, we obtain some astounding relationships between these polynomials and the extended modular group, extended Hecke groups, and extended generalized Hecke groups with geometric interpretations. We define new sequences derived from these relations.
