研究了七一Hessian算子对应的多极点忌一格林函数,得到了在k-超凸域上的连续性与边界行为,并通过Lelong-Jensen公式展示了七一Hessian边界测度与k-凸函数在极点处函数值之间的关系.
The k-Green function with several poles is studied in this paper. Its behavior on the boundary of k-hyperconvex domain and its continuity are established. Moreover, by the Lelong-Jensen formula, it is shown that k-Hessian boundary measure plays the role of harmonic measure for k-convex functions.
