The normal proof (whatever that is) that I know is based on the operational form of Taylor's theorem: f(x+ε) = e^(ε(d/dx)) f. A gap in your proof is that you have to show, since, in the proof, g is given first, that given any φ satisfying the hypotheses, we can solve for an analytic g satisfying g(a + hr^s) = φ(s)

[@maths_505]

Not a big fan of that either. Hardy's proof using residues is brilliant beyond measure.

Ramanujan seriously needs some more love. Hope yo see you cover more of his amazing work.

[@ahmetalicetin5331]

Thanks. I have been tackling with this for a while and it is nice to see a video about it from a high quality channel like you.

[@MrWael1970]

Thanks for your effort

[@123bluestorm1]

Hey, I've been following your videos for a long time now. I spent last summer watching your videos, and it has been a blast getting better at solving integrals. I do wonder if you have any recommendations for books that I can use to get familiar with the techniques you use? It would be a great pleasure, thank you so much.

I'll mention some in a Q/A video I plan on doing later this month

[@aravindakannank.s.]

we want g.h.hardys proof as soon as possible ❤

[@ashishraje5712]

Very nice

[@illumexhisoka6181]

Why is it that important when it have this many conditions ?

[@maths_505]

The conditions aren't all that bad tho.

[@Risu0chan]

I suppose we need them so that we can safely swap the integral and summmation signs (with the dominated convergence theorem, perhaps? I'm not sure)

[@csilval18]

Not a big fan of just interchanging series and integrals, at least comment on why it's possible (Fubini, dominated convergence, and why the conditions are met)

[@victormarchant217]

I can't wait to see Hardy's proof

[@RagaGian]

What kind of transformation?

[@maths_505]

Mellin transform

@@maths_505 Thanks. That's great

I have to see the proof by hardy!

I'm sorry but your r's look a lot like gammas.
