Title: Propagating Direction in the Two Species Lotka-Volterra Competition -Diffusion System
Abstract:The sign of the traveling wave speed in the two species Lotka-Volterra competition-diffiusion system under strong competition provides important information about the competitive advan tage of the species. To study the sign problem of the speed, we propose a mini-max charac terization of the coefficients in the reaction terms when the wave speed is zero. Applying our characterization, some explicit conditions under which the speed sign can be determined are obtained.

Title: The Two-Center Problem Revisited
Abstract: The two-center problem, also known as the Euler’s three-body problem, concerns the motion of a mass point in the gravitational field generated by two other mass points that are fixed in space. It is a classic example of integrable systems and is widely considered a well-understood problem. Developments and applications of variational methods in celestial mechanics in the past two decades motivate a revisit to this problem by variational approaches. In this talk I will briefly outline its history and recent discoveries from variational perspective
