Abstract :
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 suffcient conditions under which an orthogonal
series is summable jN; p; qj almost everywhere. These conditions are expressed
in terms of coeffcients of the series. It is the purpose of this paper to extend this
result to double absolute summability ǁN(2); p; qǁ k, (1 ≤ k ≤ 2).
