On the finite generation of ideals in tensor triangular geometry

Abstract Inspired by Cohen's characterization of Noetherian commutative rings, we study the finite generation of ideals in tensor triangular geometry. In particular, for an essentially small tensor triangulated category with weakly Noetherian spectrum, we show that every prime ideal in can be generated by finitely many objects if and only if the set of prime ideals of is finite.

In particular, for an essentially small tensor triangulated category with weakly Noetherian spectrum, we show that every prime ideal in can be generated by finitely many objects if and only if the set of prime ideals of is finite.
