报告摘要：Recently, many authors have studied fractional optimization problems and moment problems. The moment problems have been well known and very useful for many real problems. In this talk, we consider a fractional moment problem involving SOS convex polynomials, and obtain a linear semidefinite optimization problem by using the Lagrangian dual problem of the fractional moment problem. We show that we can obtain the solutions of the fractional moment problem from the ones of the linear semidefinite optimization problem.
