چکیده
|
In the paper [y. okuyama, on the absolute generalized norlund summability of orthogonal series, tamkang j. math. vol. 33, no. 2, (2002), 161-165] the author has found some sufficient conditions under which an orthogonal series is summable ǀn, p, qǀ almost everywhere. these conditions are expressed in terms of coefficients of the series. it is the purpose of this paper to extend this result to double absolute summability ǀn^(2); p; qǀk, (1 ≤ k ≤ 2).
