Equality of actual continuous SLE trace laws under capacity scaling. The Brownian driver laws agree by finite-dimensional uniqueness. Canonical reverse-flow approximants transfer the measurable trace factor through that law equality, so no scaling law for geometric events is assumed.

    Source documentation

    Equality of continuous driver laws gives equality of the actual trace laws. Reverse-flow approximants identify the trace factor on the common law.
