研究一元全纯函数的一个基本工具是柯西积分公式。因此,当研究区域f1上的全纯函数时。CCone想要柯西积分的适当推广。一种可能的选择是全纯函数(边值)空间上的Szego投影5‘,即L^^)正交投影。然而,除了几个特殊的领域外,S的核心并没有明确的表达。因此,要理解Szego算子的映射性质,必须估计它的核。对于严格伪凸域,这样的估计是由Fefferman[F]得到的。
A fundamental tool in the study of holomorphic functions of one complex variable is the Cauchy integral formula. Hence when studying holomorphic functions in a domain fl. C C one wants a suitable generalisation of the Cauchy integral. One possible choice is the Szego projection 5', i.e. the L^^) orthogonal projection on the space of (boundary values of) holomorphic functions. However, except for a few special domains, the kernel of S have no explicit expression. Thus to understand the mapping properties of the Szego operator one has to estimate its kernel. For strictly pseudoconvex domains such estimates were obtained by Fefferman, [F].
