The end of the proof of Lemma 6 should be corrected. Lines from 13 to the end of page 17 should read:

"Thus in view of

ç , ç _ / * o ( < * / 4 ) , if 4 II d,

1 + 4 \ 2t0(d/4, a = ± 3 (mod 8)) if 8 | d,

and

( ) s s _ ( -toW), if 4 || d,

[ J °2 + °3 ~ \ -2t0(d/4, a = ± 1 (mod 8)), if 8 | d,

we obtain

(**) t0(S, a = ± 3 (mod 8)) = 0.

Therefore (3.27) implies

tk = \ t 2 (mod 2o r d 2 k + 6) , and by Lemma 2, the lemma follows." •

As for détails, (*) follows from

d \ ( d \ f d\

(5/2 + ay \ê/2 — a J \a J

(which holds for 0 < a < 6/4: in ail the cases), and (**) is a conséquence of

t0(d/4,a = ±3 (mod 8)) = t0(d/4, a = ± 1 (mod 8)) = t0(d/8, a = -6* (mod 4)) (which holds for d = ±8d*).
