講 題:Topics on Calculus of Variation
摘 要:
In this talk, I will introduce some topics on calculus of variation, including history, classical problems and 3 problems proposed by Hilbert. In order to find a global minimizer of a functional, a direct method is involved. I also study the difference between the Dirichlet and the Neumann condition from a viewpoint of variational method. Finally, the existence of traveling waves of a reaction-diffusion equation will be constructed and wave interaction will be discussed by a variational approach.
