Radial SLE2 (source code)

= Radial SLE2
{title2=$\operatorname{radial\ SLE}_2$}

For radial <SLE> at parameter two, the normalized slit-domain <Poisson kernel> at the growing tip is a <local martingale>. This observable provides the coupling to <loop-erasure of planar Brownian motion>, oriented from the boundary point to the interior target. Its discrete counterpart is a <loop-erased random walk>.
