Abstract:

In this talk, we will discuss the logarithm of the central value L(12,χD) in the symplectic family of Dirichlet L-functions associated with the hyperelliptic curve of genus g over a fixed finite field Fq in the limit as g. Unconditionally, we show that the distribution of log|L(12,χD)| is asymptotically bounded above by the full Gaussian distribution of mean 12logdeg(D) and variance logdeg(D), and also log|L(12,χD)| is at least 94.27% Gaussian distributed. Assuming a mild condition on the distribution of the low-lying zeros in this family, we obtain the full Gaussian distribution.
