Asymptotic Mahler measure conjecture for Gaussian periods

Let αn\alpha_n be the Gaussian-period algebraic integer defined in the paper, and let m(αn)\mathrm{m}(\alpha_n) denote its Mahler measure. For a property of odd integers nn, say that it holds almost always if it fails for only o(X)o(X) odd values of nXn\leqslant X as X+X\rightarrow +\infty. Asymptotic Mahler measure conjecture. We have

m(αn)nloglogn\mathrm{m}(\alpha_n)\asymp n\log{\log{n}}

for all but o(X)o(X) odd values of nXn\leqslant X as X+X\rightarrow +\infty. This conjecture gives a precise typical growth rate for the Mahler measure of the Gaussian periods; the paper presents it as a conjectural refinement of the unconditional bounds nm(αn)nlognn\ll \mathrm{m}(\alpha_n)\ll n\log n.
