报告摘要: In this talk, we will discuss the spectralproperties of Dirac operators. First, we will go overthe physical background and geometric characteristics of Dirac operators. Then we willgive the variational characterization of eigenvaluesin gaps of the essential spectrum of Diracoperators. At last, we will explain how to study theSpectrum Zero Problem of nonlinear Diracequations by using spectral projections of Diracoperators.
