Ah, I see, thanks! If you want to chat off-line, perhaps you could drop me an email (ir40@st-andrews.ac.uk)?

Thanks! There is another form of the remainder term in Kurokawa's paper - I assume that does not make things easier?!

I don't know what question you want to ask, and you do, so...\

comment Interpolating Product of two Polynomials
For one thing, you define the polynomial $A$ at least two (and maybe three) times.

comment Probability of random geodesics on the half-sphere intersecting
But the OP asks about a hemisphere, which your map does not act on.

@BorisBukh math.se is probably a better place, but the answer is not completely obvious.

That is very interesting! Is the constant in the $O$ independent of $f?$

comment Two rational and one irrational root of a cubic?
Not research level. Hint look at the constant term.

comment Improper integral $\int_0^1 \frac{\exp(ctx)}{\sqrt{(\exp(bt)-1)(1-\exp(atx))-(1-\exp(at))(\exp(btx)-1)}} dx$ with $-a$ and $b$ positive
@H.Berbeleque The singularity (in both cases) is at $0,$ and you only ask for real analyticity for $t>0.$
