Continuum nonsimple loops and 2D critical percolation

Research output: Contribution to journalArticlepeer-review


Substantial progress has been made in recent years on the 2D critical percolation scaling limit and its conformal invariance properties. In particular, chordal SLE 6 (the Stochastic Loewner Evolution with parameter κ=6) was, in the work of Schramm and of Smirnov, identified as the scaling limit of the critical percolation "exploration process." In this paper we use that and other results to construct what we argue is the full scaling limit of the collection of all closed contours surrounding the critical percolation clusters on the 2D triangular lattice. This random process or gas of continuum nonsimple loops in {\Bbb R} 2 is constructed inductively by repeated use of chordal SLE 6. These loops do not cross but do touch each other - indeed, any two loops are connected by a finite "path" of touching loops.
