»ã±¨ÌáÒª£ºIn this talk, for Siegel modular forms of degree two weight two, we construct a basis of its subspace of Siegel Eisenstein series of square-free level N, and compute their Fourier coefficients explicitly. In addition, we connect the theta series from Yoshida lifting associated to Eichler orders with Siegel Eisenstein series.
