Let $L(s)=\sum a_n n^{-s}$ be an ordinary Dirichlet series with entire continuation of order at most $1$, and let $\mu(\sigma)$ denote its order function on vertical lines. Refined…

Let $L(s)=\sum a_n n^{-s}$ be an ordinary Dirichlet series with entire continuation of order at most $1$, or meromorphic continuation with finitely many poles. Define the order fun…
