This paper is a study of the complex Monge-Amp~ re operator (ddC) n. Let~ be an open and bounded subset of C'~. If ujCC2 (~), l~ j~ n, then the Monge-Amp~ re operator operates on (ul,..., un) and equals ddeulA... AddCun, where d= O+ O and d~= i (OO).If also each uj is plurisubharmonic, then dd~ ulA... Addr is a positive measure. This operator is of great importance in pluripotential theory, where it plays a role similar to that of the Laplace operator in classical potential theory. The Laplace operator is a linear, second-order differential operator and thus is defined on all distributions on ft, while the complex Monge Ampere operator is non-linear and cannot be defined on all plurisubharmonic functions on gt, cf.[14],[20] and [8]. Moreover, the operator is discontinuous in the weak*-topology, cf.[9]. On the other hand, it was shown by Bedford and Taylor [2] that (dde) n is welldefined on all locally bounded plurisubharmonic functions. The problem of extending the domain of definition beyond PSHNL~ oe and describing the corresponding range has been studied by several authors:[2],[3],[8],[13],[15],[16] and [17]. See [1] for a survey on pluripotential theory. In particular, w of that paper contains a discussion of the domain of definition for (dd~) n. In this paper, we define certain classes gp and 9Cp of plurisubharmonic functions, and study the complex Monge-Amp~ re operator (ddC) on them.
