讲座摘要:The classical $L^2$ approach is a basic tool in complex analysis of several variables. Naturally, one expected to extend it to infinite-dimensional complex analysis, but this is a longstanding unsolved problem. The main purpose in this work is to establish $L^2$ estimates and existence theorems for the $\overline{\partial}$ operators in general pseudo-convex domains of infinite dimensions. For this purpose, we introduce several new techniques, which have independent interest to be adopted to study some other problems in infinite-dimensional analysis. (This is a joint work with Zhouzhe Wang and Jiayang Yu).
