Geometric description of some Loewner chains with infinitely many slits

We study the chordal Loewner equation associated with certain driving functions that produce infinitely many slits. Specifically, for a choice of a sequence of positive numbers $(b_n{)}_{n\ge 1}$ and points of the real line $(k_n{)}_{n\ge 1}$, we explicitily solve the Loewner PDE $${\displaystyle \frac{\mathrm{\partial }f}{\mathrm{\partial }t}}(z,t)=-f^{\mathrm{\prime }}(z,t)\sum _{n=1}^{+\mathrm{\infty }}{\displaystyle \frac{2b_n}{z-k_n\sqrt{1-t}}}$$ in $\mathbb{H}\times [0,1)$. Using techniques involving the harmonic measure, we analyze the geometric behaviour of its solutions, as $t\to 1^{-}$.
