Eisenstein series part of the primitive representations for even rank quadratic forms

Number Theory 2024-11-27 v2

Abstract

In this paper, we first investigate the relationship between the number of primitive representations of nn by quadratic forms and the number of non-primitive ones. We hence obtain a theorem to deal with the Eisenstein series part with quadratic Dirichlet character when deriving the formula for the number of primitive representations of an integer nn by even rank quadratic forms from the number of non primitive ones. Formulas for special cases are given as examples.
