Abstract
Chordal SLEκ(ρ_) is a natural variant of the chordal SLE curve. It is a family of random non-crossing curves on the upper half plane from 0 to ∞, whose law is influenced by additional force points on R. When there are force points away from the origin, the law of SLEκ(ρ_) is not reversible, unlike the ordinary chordal SLEκ. Zhan (2019) gives an explicit description of the law of the time reversal of SLEκ(ρ_) when all force points lie on the same sides of the origin, and conjectured that a similar result holds in general. We prove his conjecture. Specifically, based on Zhan’s result, using the techniques from the Imaginary Geometry developed by Miller and Sheffield (2013), we show that when κ∈(0,8), the law of the time reversal of non-boundary filling SLEκ(ρ_) process is absolutely continuous with respect to SLEκ(ρˆ_) for some ρˆ_ determined by ρ_, with the Radon-Nikodym derivative being a product of conformal derivatives.
