We consider a class of generalized harmonic functions in the open unit disc in the complex plane. Our main results concern a canonical series expansion for such functions. Of particular interest is a certain individual generalized harmonic function which suitably normalized plays the role of an associated Poisson kernel.

广义调和函数的级数展开

我们考虑复平面中开单位圆盘中的一类广义调和函数。我们的主要结果涉及此类函数的规范级数展开。特别令人感兴趣的是某个单独的广义调和函数，它适当地归一化，起到相关泊松核的作用。
