Nahm's Equations and Rational Maps from $\mathbb{C}{\mathrm{P}}^1$ to $\mathbb{C}{\mathrm{P}}^n$

We consider Nahm’s equations on a bounded open interval with first order poles at the ends. By imposing further boundary conditions, extended moduli spaces are identified with spaces of rational maps from $\mathbb{C}{\mathrm{P}}^1$ to $\mathbb{C}{\mathrm{P}}^n$. Having the residues at one end define sums of irreducible representations of $\mathfrak{s}\mathfrak{u}(2)$, the dimensions of those summands correspond to holomorphic charge on the rational map side. Technical difficulties arise due to half powers in the boundary conditions. Further, a symplectomorphic identification with moduli spaces corresponding to spaces of rational maps into complete flag varieties is given.
