Boundary-point Bessel flow for SLE (source code)

= Boundary-point Bessel flow for SLE
{c}

For chordal $\operatorname{SLE}_\kappa$, the centered image of a real boundary point, divided by $\sqrt\kappa$, evolves as a <Bessel process> of dimension
$$
d=1+\frac4\kappa.
$$
Its first hit of zero is the time at which the point is swallowed by the Loewner hull.
