Lambert theorem, convex optimization, and minimizing solutions of the n-body problem

Abstract: Abstract: The Lambert problem concerns the Kepler problem as a boundary value problem. A celebrated theorem by Lambert and Lagrange states that the transfer time is functionally dependent on the distance between the two ends, the sum of orbital distances from the attractive focus, and the semimajor axis. In this talk I will briefly present an intriguing linkage between this beautiful theorem and minimizing solutions of the n-body problem, through certain convex optimization techniques.
