The sine-process maximum-growth conjecture at zero shift

About 7 years old · traced to

Let XX be a configuration sampled from the sine process, let GX+iAG_{X+iA} be the associated random entire function, and define

MA(T)=max⁡t:∣t∣<Tlog⁡∣GX+iA(t+iA)∣.M_A(T)=\max_{t:|t|<T}\log\lvert G_{X+iA}(t+iA)\rvert.

For A>0A>0, the known asymptotic is

lim sup⁡T→∞MA(T)log⁡T=2.\limsup_{T\to\infty}\frac{M_A(T)}{\log T}=\sqrt{2}.

The sine-process maximum-growth conjecture at zero shift. The same asymptotic formula holds for A=0A=0:

lim sup⁡T→∞max⁡t:∣t∣<Tlog⁡∣GX(t)∣log⁡T=2.\limsup_{T\to\infty}\frac{\max_{t:|t|<T}\log\lvert G_X(t)\rvert}{\log T}=\sqrt{2}.

The supplied text states the formula for positive shifts and leaves the zero-shift case as an interesting direction.
