 Abstract:

      The Linear-Quadratic (LQ) control problem without time consistence was inspired by the mean-variance portfolio selection in a continuous time financial market. Control problems without time consistence has been studied by many researched,  especially in the last 5 years. But most literature focus on the framework and adhoc construction of solutions for special classes,  including our work on for the LQ problem. In this paper, we prove that the solution we obtained in our previous work is the only one.  This is the first uniqueness of solutions to a time inconsistent problem in literature.
