Apr 13 at 4:57	comment	added	Pietro Majer		You are right: I realised that $\phi(t)-\psi(t)=o(t)$ as $t\to-\infty$ is much easier to prove, and it is sufficient to conclude

Apr 12 at 17:30	comment	added	CWC		Thank you. This is surprising and counter-intuitive to me. In your proof, the step that I am slightly confused with is the part where you show $\phi(t)-\psi(t) = o(1)$ by the dominated convergence theorem. It might be something trivial, but could you please elaborate?
Apr 12 at 16:15	comment	added	Pietro Majer		Please ask, is something is not clear
