Equality of the tight hyperbolic and hyperbolic minimal discrepancy densities

About 10 years old · traced to

Let ρH\rho_{\mathbb{H}} be the minimal discrepancy density for hyperbolic zero packing, and let ρH∗\rho_{\mathbb{H}}^\ast be the minimal discrepancy density for tight hyperbolic zero packing, defined by

ρH∗=lim inf⁡r→1−inf⁡f∫DΦf(z,r)dA(z)1−∣z∣2log⁡11−r2,\rho_{\mathbb{H}}^\ast=\liminf_{r\to1^-}\inf_f\frac{\int_{\mathbb{D}}\Phi_f(z,r)\frac{\mathrm{d} A(z)}{1-|z|^2}}{\log\frac{1}{1-r^2}},

where Φf(z,r)=((1−∣z∣2)∣f(z)∣−1D(0,r)(z))2\Phi_f(z,r)=\big((1-|z|^2)|f(z)|-1_{\mathbb{D}(0,r)}(z)\big)^2. Equality conjecture. We believe that ρH∗=ρH\rho_{\mathbb{H}}^\ast=\rho_{\mathbb{H}}. This would identify the optimal asymptotic discrepancy for tight hyperbolic zero packing with the usual hyperbolic minimal discrepancy density; the source provides no resolution.
