利用余面积公式得到了超调和函数的可积性和次调和函数的不可积性。结果涉及到格林函数。对于某个区域,例如Lipschitz域,我们估计格林函数,并用到边界的距离来重述结果。S(X)((g(X))IVG(X)I2dx>CN S(Xo)(o(T)dt)。
We apply the coarea formula to obtain integrability of superhar- monic functions and nonintegrability of subharmonic functions. The results involve the Green function. For a certain domain, say Lipschitz domain, we estimate the Green function and restate the results in terms of the distance from the boundary. r P~~~~~~~~~~~00 s(x) ((g(x))IVg(x)I2 dx > Cn S(xo) ( o(t)dt.
