| contents | This is a reworked version of the paper.
An idea that allows us to circumvent limitations of previous approaches is not to apply arithmetic-geometric mean inequality and the second moment asymptotics to the entire segment $[1/2-a/\log T+iT,1/2-a/\log T+i2T]$ but use them on a subset only, and use the integral of logarithm of the mollified function on the complement.
Ultimately, the result depends on the exponent in the zero-density estimate near the critical line, which leads to the relation between the magnitude of $\widetilde{V}^{1/2}$ and the measure of the exceptional set in Theorem 4, Section 2.3. The exponents of Jutila and Conrey are enough for our purposes.
We provide more details on an effective approximation of $1/z$ using the Schwarz-Christoffel mapping. This is needed in the construction of the mollifier.
One observation on why the approach is feasible is that the functional equation established in the paper allows one to shift the segment of integration $[1/2-a/\log T+iT,1/2-a/\log T+i2T]$ to $[1/2+A/\log T+iT,1/2+A/\log T+i2T]$. A result of Selberg allows for a proof that almost all of zeros of our integrand are to the left of the shifted segment. |
