Abstract

We show that, for κ(0,8)\kappa\in(0,8), the integral of the laws of two-sided radial SLEκ_\kappa curves through different interior points against a measure with SLEκ_\kappa Green function density is the law of a chordal SLEκ_\kappa curve, biased by the path's natural length. We also show that, for κ>0\kappa>0, the integral of the laws of extended SLEκ(8)_\kappa(-8) curves through different interior points against a measure with a closed formula density restricted in a bounded set is the law of a chordal SLEκ_\kappa curve, biased by the path's capacity length restricted in that set. Another result is that, for κ(4,8)\kappa\in(4,8), if one integrates the laws of two-sided chordal SLEκ_\kappa curves through different force points on R\mathbb R against a measure with density on R\mathbb R, then one also gets a law that is absolutely continuous w.r.t. that of a chordal SLEκ_\kappa curve. To obtain these results, we develop a framework to study stochastic processes with random lifetime, and improve the traditional Girsanov's Theorem.
