Esakia status of Spec(C(βN))

Ascertain whether the prime spectrum Spec(C(βN)) of the ring of real-valued continuous functions on the Stone–Čech compactification βN of the natural numbers is an Esakia space.

Background

Within the broader open problem of characterizing all T with Esakia Spec C(T), the authors single out the specific case of T = βN. They report no known example of an infinite compact Hausdorff T with Esakia Spec C(T), making βN a natural test case.

Resolving this question would provide insight into whether any infinite compact Hausdorff examples exist and would inform the general characterization problem.

In particular, we do not know whether Spec(C(3IN)) is Esakia.
