Understanding the problem

Read the background

Every complex C∗-algebra in which each positive element is properly infinite is strongly purely infinite, satisfying the full positive-element diagonalization property.

Why it matters

If correct, resolves the ordinary-to-strong implication without exactness, nuclearity, unitality or simplicity assumptions.

What counts as progress

Does proper infiniteness of every positive element imply strong pure infiniteness?
