| Research Abstract |
In this research, we found a recursion formula for local densitires, which is useful to give an explicit formula for local desities. Further applying this to Sigel-Eisenstein series, we gave several important results about the Fourier coefficients of Siegel-Eisenstein series.
First, we gave a precise information about the denominator of a power series of one variables defined by Y.Kitaoka.
Secondly, we gave an explicit formula for the Fourier coefficients of Siegel-Eisenstein series of degree 3.
Thirdly, we gave an explicit formula for Koecher-Maass Dirichlet series associated with Siegel-Eisenstein series. This is a joint work with T.Ibukiyama.
Finally we gave a precise information about the denominaotor and numerator of a power series of several variables attached to local densities of quadratic forms.
