Thread-set conjecture for iterated localizations of stratified tensor triangulated categories
Thread-set conjecture for iterated localizations of stratified tensor triangulated categories
Let be a rigidly-compactly generated tensor triangulated category, stratified in the sense of Balmer–Favi, whose Balmer spectrum is noetherian and has finite Krull dimension. For a tuple of subsets of , a thread set is a chain containing elements with . Let denote the associated iterated localization.
Thread-set conjecture. Let and be tuples of subsets of . If they have the same thread sets, then there is a canonical natural isomorphism
The conjecture proposes that the composition of localizations is determined by the combinatorics of chains of Balmer primes in the indexing subsets, and hence by the Balmer spectrum. Its status is not resolved in the supplied source.
