Integrability theorems for power series expansions of two variables

Yoshimitsu Hasegawa

Vol. 46 (1973), No. 2, 419–428
Abstract

Let f(x,y) = Σm,n=0am,nxmyn in the triangle x + y 1, x,y 0, or in the quarter-disk x2 + y2 < 1,x,y 0. This paper show some relations between L-integrability of f(x,y), with certain multipliers, and the coefficients am,n.
