Thanks! With your hint it was very easy to solve :-)

comment Multiplication of two asymptotic expansions
Ok, I understand now better. But if you do that, then you get the above series, don't you?

comment Multiplication of two asymptotic expansions
Hello Kelenner. If I do the calculations as you said it, I get exactly the same series as above, formally at least. So either I misunderstood you or the problem remains the same: Why is the above claim correct, i.e. why is the given formal series an asymptotic expansion for $f(t)\cdot g(t)$ ??

comment Non congruent (spherical) quadrilateral with same angles
Hello Mark, thank you for your help. I'm not sure if I understand you correctly. First of all, the "fraternal twin parallelograms" you described above seem to be congruent since they differ just by a reflection in the plane (tell me if I'm wrong). Secondly, what do you mean here: "Now choose among that family of quadrilaterals two very small ones which are close to a pair of planar fraternal twin parallelograms, having a corner angle of 2πα." What exactly means "close to". Furthermore you write: "they will have very nearly equal areas and perimeters on the sphere". Can you tell me why?
