Abstract:
<br />
Substantial progress has been made in recent years on the 2D
<br />
critical percolation scaling limit and its conformal invariance
<br />
properties.In particular, chordal SLE_6 (the Stochastic Loewner
<br />
Evolution with parameter 6) was, in the work of
<br />
Schramm and of Smirnov, identified as
<br />
the scaling limit of the critical percolation ``exploration process.''
<br />
In joint work with Federico Camia, we use that and other results to
<br />
construct what we argue is the full scaling limit of the
<br />
collection of all closed
<br />
contours surrounding the critical percolation clusters on the 2D
<br />
triangular lattice.
<br />
This random process or gas of continuum nonsimple loops in
<br />
the plane is constructed
<br />
inductively by repeated use of chordal SLE_6.
<br />
These loops do not cross but do touch each other ---
<br />
indeed, any two loops are connected by a finite ``path'' of touching
<br />
loops.
