In this talk, we will define the Fourier expansion of a Siegel modular form. We prove the Koecher's principle and use it to show the non existence of Siegel forms of certain weight. We define the Siegel operator on the space of modular forms, and define the space of cusp forms as the kernel of this operator. We end with examples of Klingen Eisenstein series.
