The limiting density measure conjecture for minimal membranes

About 6 years old · traced to

Let LL be a unimodular loop. For a loop LL, let μL\mu_L be the probability distribution on cloud(L)⊂Zn\mathrm{cloud}(L)\subset\mathbb Z^n defined by the normalized incidence count of lattice points in uniformly chosen minimal membranes, and define μL,t(a):=μtL(ta)\mu_{L,t}(a):=\mu_{tL}(ta). Let S⊂RnS\subset\mathbb R^n be a limit surface.

Limiting density measure conjecture for minimal membranes. As t→∞t\to\infty, the measures μL,t\mu_{L,t} converge to a limit measure

μL,∞:=lim⁡t→∞μL,t\mu_{L,\infty}:=\lim_{t\to\infty}\mu_{L,t}

supported on a limit surface S⊂RnS\subset\mathbb R^n.

This conjecture proposes a limiting density for lattice points on random minimal membranes and relates its support to the limit surface arising from membrane dilation. The supplied text gives no resolution status.
