Although there is a great deal of research on Riemann's two papers, there are yet some content and formulas not being studied thoroughly. The most typical example is the following formula
$$
\pi^{-\frac{s}{2}}\Gamma(\frac{s}{2})\zeta(s)=2\Re(\pi^{-\frac{s}{2}}\Gamma(\frac{s}{2})f(s))\qquad\Re(s)=1/2,
$$
nobody has pointed out why Riemann gave it since 1932. This is Riemann's conclusion in his nachlass.
