= Chordal SLE4
{title2=$\operatorname{SLE}_4$}

Chordal <SLE> at parameter four has driver $2\beta_t$ in half-plane-capacity time. The <Itô formula> makes the imaginary part of $\log(g_t(z)-W_t)$ drift-free, a feature used in the <SLE4 coupling with a Gaussian free field>. The trace is simple and avoids fixed nonzero boundary points.
