Insights into Mathematics | Multiplicative functions and Dirichlet Series via Boxes II| Math Foundations 243 | N J Wildberger @njwildberger | Uploaded 1 month ago | Updated 17 hours ago
We introduce Dirichlet series, which are particular series coming from number theory, generalizing the Riemann zeta function, in a somewhat novel way using box arithmetic. Let's try to avoid nonsensical appeals to "doing an infinite number of things", and instead give a precise arithmetic with always well-defined objects. The natural operations of Box Arithmetic start with addition, then multiplication and then the caret operation, which we could call "caretation".

By combining addition and caretation, we get an algebraic structure which effectively encodes the usual Dirichlet series. But we are able to think about the associated algebra in quite an interesting alternative way, including insights into novel notation.
