symmetric monoidal (∞,1)-category of spectra
The concept of tensor triangulated category, may be thought of as a categorification of the concept of a ring in that the monoidal category structure refines the monoid structure of a ring, and the fact that it is a triangulated category and hence stable makes it the homotopy theory analog of a monoid in abelian groups, hence of a ring.
Accordingly, one may consider the prime spectrum of a tensor tringulated category in direct analogy: the prime ideals are taken to be the thick subcategories which behave as prime ideals under the tensor product, in the obvious way. (Thomason 97, Balmer 02).
In terms of modern stable (∞,1)-category theory this may be understood as being the shadow on homotopy categories of the prime spectrum of a symmetric monoidal stable (∞,1)-category.
A typical application of the spectrum construction for tensor triangulated categories is to the derived categories of quasicoherent sheaves of algebraic varieties. If one restricts to perfect complexes then often the variety may be reconstructed from the spectrum of its category of coherent sheaves. More generally this reconstruction theory applies to geometric stacks, see at Tannaka duality for geometric stacks.
In some good cases such reconstruction works even when forgetting the monoidal structure (Bondal-Orlov 03): The reconstruction theorems of nice classes of schemes from the abelian categories of (quasi)coherent sheaves have versions from weaker data of the corresponding derived categories, viewed as triangulated or enhanced triangulated categories (see triangulated categories of sheaves). This is important for study of deformations, homological mirror symmetry and noncommutative generalizations.
An important theorem of reconstruction using the triangulated category (but not the monoidal structure) is the Bondal-Orlov reconstruction theorem:
Several spectra for triangulated categories were systematically studied by Rosenberg:
Along the lines of the general spectral cookbook, these spectra are obtained considering certain preorders on objects of the triangulated category. The preorders can be easily modified to respect additional structure, say a monoidal product, if there.
In this vein, Thomason, Balmer, Garkusha and others considered instead tensor triangulated categories and corresponding spectral theory, as well as stronger reconstruction theorems of schemes from derived categories of coherent sheaves (or, in some cases, perfect complexes) taking into account the monoidal structures:
