A General Dirichlet series is a type of series that is often studied in number theory and complex analysis. A Dirichlet series is a series of the form: \\\[ D(s) = \\sum_\{n=1\}^\{\\infty\} a_n n^\{-s\} \\\] where \\( s \\) is a complex variable, \\( a_n \\) are complex coefficients, and \\( n \\) runs over positive integers.
