symmetric monoidal (∞,1)-category of spectra
A Banach ring is a complete normed ring, hence a commutative monoid in the monoidal category of complete normed groups (with short group homomorphisms and the projective tensor product).
If not just in complete normed groups but in complete normed vector spaces (Banach spaces), then this is a Banach algebra.
The Berkovich spectrum of a Banach ring is the topological space of multiplicative seminorms on that are bounded by the norm on .
The integers equipped with their absolute value norm are a Banach ring.
The integers with the -adic norm are an incomplete normed ring whose completion is the Banach ring of -adic integers.
