| Abstract: |
| This paper investigates the estimation problem of Dedekind sums involving the bi-periodic Fibonacci {fn} and Lucas {ln} sequence. By utilizing the analytic properties of the Dedekind sum S(h， k), and the recurrence relations of bi-periodic Fibonacci {fn} and Lucas {ln} sequence, we derive asymptotic estimates for the sums Σn=1m (S (f2n, f2n+1) + S (f2n+1, f2n+2)) and Σn=1m (S (l2n, l2n+1) + S (l2n+1, l2n+2)). This work extends the study of Dedekind sums from linear recurrence sequences to the nonlinear recurrence sequences. |
