The ring-structure reconstruction conjecture for the prismatized sphere
Let be the syntomic stack and let be its associated monoid stack. Let and denote their pullbacks to . Ring-structure reconstruction conjecture. The map
identifies the source with the stack of ring structures on . This is expected to follow from the main theorem cited in the source together with the non-functoriality of Raksit's height at least one deformed filtered de Rham complexes for rings.
