The invariant partial ideal characterization conjecture for -algebras
The invariant partial ideal characterization conjecture for -algebras
Let be a -algebra. A partial ideal assigns an ideal to each commutative sub--algebra compatibly with inclusions, and it arises from a total ideal when . A partial ideal is invariant when, for every commutative sub--algebra and every unitary ,
Invariant partial ideal conjecture. A partial ideal of a -algebra arises from a total ideal if and only if it is an invariant partial ideal. Consequently, the map is a bijective correspondence between total ideals and invariant partial ideals.
This conjecture seeks to characterize exactly which partial ideals are induced by closed two-sided ideals, using invariance under inner automorphisms. The supplied text gives no resolution status.
