Non-singleton intersection conjecture for pairs of Liouville quantum gravity geodesics

About 1 year old · traced to

Fix γ∈(0,2)\gamma\in(0,2), a whole-plane Gaussian free field hh, and distinct points z1,z2,z3,z4∈Cz_1,z_2,z_3,z_4\in\mathbb{C}. Let Γzi,zj\Gamma_{z_i,z_j} denote a geodesic from ziz_i to zjz_j in the metric DhD_h. Non-singleton intersection conjecture. Almost surely,

Γz1,z2∩Γz3,z4\Gamma_{z_1,z_2}\cap\Gamma_{z_3,z_4}

cannot be a singleton. The analogous statement is not known for γ\gamma-LQG and appears to be unknown even for Brownian geometry; it would rule out a type of isolated intersection relevant to the classification of geodesic networks and the multiplicity of their points.
