Eisenstein series and convolution sums
We compute Fourier series expansions of weight 2 and weight 4 Eisenstein series at various cusps. Then we use results of these computations to give formulas for the convolution sums ∑a+pb=nσ(a)σ(b), ∑p1a+p2b=nσ(a)σ(b) and ∑a+p1p2b=nσ(a)σ(b) where p,p1,p2 are primes.
