Abstract

For a Kähler manifold $X$ equipped with a prequantum line bundle $L$, we give a geometric construction of a family of representations of the Berezin–Toeplitz deformation quantization algebra $(C^\infty (X) [[\hbar]], \star_{BT})$ parametrized by points $z_0 \in X$. The key idea is to use peak sections to suitably localize the Hilbert spaces $H^0 (X, L^{\otimes m})$ around $z_0$ in the large volume limit.
