报告摘要:
In this talk, we first prove that the mean-field stochastic linear quadratic (MFSLQ) control problem with random coefficients has a unique optimal control and derive a preliminary stochastic maximum principle to characterize this optimal control by an optimality system. However, because of the term of the form $\mathbb{E}[A(\cdot)X(\cdot)] $ in the adjoint equation, which cannot be represented in the form $\mathbb{E}[A(\cdot)]\mathbb{E} [X(\cdot)] $, we cannot solve this optimality system explicitly. To this end, we decompose the MFSLQ control problem into two constrained SLQ control problems without the mean-field terms. These SLQ control problems can be solved explicitly by an extended LaGrange multiplier method. This talk is based on a joint paper with Wen Xu.
