J. R. Wilton obtained a formula for the product of two Riemann zeta functions. This formula played a crucial role to find an approximate functional equation for the product of two Riemann zeta functions in the critical region. We find an analogous formula for the product of two Dedekind zeta functions and then use this formula to find the values of Dedekind zeta function attached to an arbitrary imaginary quadratic field at any positive integer. We finally compute some values of Dedekind zeta functions attached to certain imaginary quadratic fields. 查看全文>>
