Abstract

Denote the n-th convergent of the continued fraction by pₙ/qₙ = [a₀;a₁,...,aₙ]. We give some explicit forms of leaping convergents of Tasoev continued fractions. For instance, [0;ua,ua²,ua³,...] is one of the typical types of Tasoev continued fractions. Leaping convergents are of the form

\frac{p_{r n + i}}{q_{r n + i}}

(n=0,1,2,...) for fixed integers r ≥ 2 and 0 ≤ i ≤ r-1.
