In algebraic geometry and topology, a **sheaf of spectra** is typically a construction involving the **spectrum** of a commutative ring or a more general algebraic structure. To understand this concept, we first need to clarify some terms: 1. **Spectrum of a ring**: The spectrum of a commutative ring \\( R \\), denoted as \\( \\text\{Spec\}(R) \\), is the set of prime ideals of \\( R \\).
