Riemann-type functional equations

We study Riemann-type functional equations with respect to value-distribution theory and derive implications for their solutions. In particular, a fixed complex number $a\neq0$ function from the Selberg class $\mathcal{L}$, we prove Riemann-von Mangoldt formula of a-points $\Delta$-factor equation $\mathcal{L}$ an analog Landau's over these points. From last that ordinates $a$-points are uniformly distributed modulo one. Lastly, show existence mean-value values $\mathcal{L}(s)$ taken at
