摘要
代数族V上关于特殊的函数u=log(1+|z|)的Phragmén-Lindelf条件PL(Ω)与APL(Ω)条件之间的关系已有很多研究,为更好地研究常系数线性偏微分算子右逆的性质提供了新的途径和方法.对更为一般的关于权函数ω(z)的Phragmén-Lindelf条件,借助代数族V的正则点上的多重次调和函数u,得到了PL(Ω,ω)条件与APL(Ω,ω)条件的等价性,通过选择适当的Phragmén-Lindelf条件更好地刻画了常系数线性偏微分算子P(D)的线性连续右逆的存在性.
Some recent papers have investigated the relationship between PL(Ω) and APL(Ω) for special functions u of the form u = log(1 +|z|) in algebraic variety V, which have provided new approach and method for studying the properties of right inverse of constant coefficient linear partial differential operators. For more general Phragmon-Lindelof condition for weight function ω (z), with the help of plurisubharmonic functions u at the regular points of V, the equivalence between PL(D) and APL(g2) conditions was ob- tained. Therefore, the existence of linear continuous right inverse for constant coefficient linear partial differ- ential operators P(D) can be characterized using suitable Phragmon-Lindelof condition.
