Oddities of evenness

The $L$-function $L(A,s)$ of an abelian variety $A/F$ over a number field is conjectured to satisfy a functional equation relating $s$ and $2-s$ (this is known in many cases if $F$ is totally real). A …

Should one attack hard problems?

I think Markus Redeker's answer captures the essential point. If the problem is hard and famous (at least in the relevant sub-field), so a fortiori for a problem like P≠NP, I would add the further res …

I don't think $\textbf{L'endoscopie tordue n'est pas si tordue}$ (Twisted endoscopy is not so twisted) de J.-L. Waldspurger has been mentioned yet.

The current status of the Birch & Swinnerton-Dyer Conjecture

There is an article of J.Parson and B.Gross (On the local divisibility of Heegner points) from which I think some very very special instance of r=2, d=2 can be deduced. The argument is a combination o …
