The unitary-invariance conjecture for partial ideals of -algebras
The unitary-invariance conjecture for partial ideals of -algebras
Let be a unital -algebra. A partial ideal is a choice of a closed ideal in each unital commutative sub--algebra such that, whenever , one has . A total ideal is a closed two-sided ideal of . Unitary-invariance conjecture. A partial ideal of a unital -algebra arises from a total ideal if and only if it is fixed by every unitary rotation, meaning that for every unitary . This criterion would characterize precisely the partial ideals corresponding to closed two-sided ideals and would imply the closed-sets extension conjecture. The source does not state a resolution.
