   • 2015, Richard Kenyon, Jason Miller, Scott Sheffield, David B. Wilson, “Bipolar orientations on planar maps and SLE$_{12}$”, in arXiv‎^[1]:

     We give bijections between bipolar-oriented (acyclic with unique source and sink) planar maps and certain random walks, which show that the uniformly random bipolar-oriented planar map, decorated by the "peano curve" surrounding the tree of left-most paths to the sink, converges in law with respect to the peanosphere topology to a ${\sqrt {4/3}}$-Liouville quantum gravity surface decorated by an independent Schramm-Loewner evolution with parameter $\kappa =12$ (i.e., SLE$_{12}$).
