『 Problems and results on Hardy's Z-function 』

内容:
The title is self-explanatory: G.H. Hardy first used the function
$Z(t)$ to show that there are infinitely many zeta-zeros on the
critical line $\Re s = 1/2$. In recent years there is a revived
interest in this function, with many results and open problems.
