Abstract
A hyperkähler manifold M has a family of induced complex structures indexed by a two-dimensional sphere \(S^2 \cong \mathbb {CP}^1\). The twistor space of M is a complex manifold \({{\,\mathrm{Tw}\,}}(M)\) together with a natural holomorphic projection \({{\,\mathrm{Tw}\,}}(M) \rightarrow \mathbb {CP}^1\), whose fiber over each point of \(\mathbb {CP}^1\) is a copy of M with the corresponding induced complex structure. We remove one point from this sphere (corresponding to one fiber in the twistor space), and for the case of \(M = {\mathbb {R}}^{4n}\), \(n\in {{\mathbb {N}}}\), equipped with the standard hyperkähler structure, we construct one quantization that replaces the family of Berezin–Toeplitz quantizations parametrized by \(S^2-\{ pt\}\). We provide semiclassical asymptotics for this quantization.
