comment approximate vanishing in Pontryagin dual
thank you very much!! Indeed, this question arose from a failed attempt to solve a research problem. The original problem is still not solved, maybe it is still interesting for you, so let me mention it below.

comment When two projections in a C*-algebra are “almost” Murray-von Neumann equivalent, they are equivalent
Intuitively, maybe we can first show that when $aa^*$ is close to $p$, then the range projection of $aa^*$, denote it by $r_1$, is close to $p$, maybe the assumption is strong enough to imply $||r_1-p||<1$, so they are unitary equivalent, do the same thing for $q$, note that $r_1, r_2$ are unitary equivalent.
