摘要：In this talk, I will begin with a brief review of physical and geometric background of the Dirac operator, along with the spectral structure and orthogonal decomposition. Then I will introduce the definitions of action and energy ground states of nonlinear Dirac equations and discuss key properties such as existence, nonrelativistic limits, and convergence rates.
