The modular group and negative continued fractions play key roles in the development of a theory of reduction of binary quadratic forms with integer coefficients, as in [7]. In this paper we generalize from the modular group to the Hecke groups by replacing 1 1 0 1 with 1 λ 0 1 for certain values of λ between 1 and 2. We use Rosen's negative λ-continued… CONTINUE READING
