Corrigendum: Elliptic Curves and Quadratic Recurrence Sequences

The statement of the numerical values and z₀ on page 167 of1, Section 3] contained an error. The values that were actuallyused were (to nine decimal places): thesebeing shifted, by the periods 2₁ and 2₃ respectively, comparedwith the values given in 1] (with ₁ = 1.496729323 and ₃ = 1.225694691i).With ₀ = ₁ and (z) denoting the sigma function (z; g2, g3) withinvariants g2 = 4, g3 = –1 associated with the ellipticcurve given by equation (3.2), these values of and z₀ yield and the latter three values all agreewith those stated in the paper (apart from rounding down thelast digit in the imaginary part of A). 2000 Mathematics SubjectClassification 11B37 (primary), 33E05, 37J35 (secondary).
