Abstract

We show that the pure state evaluation map from Mn(C) M_{n}(\mathbb{C}) to C(CPn1) C(\mathbb{C} \mathbb{P}^{n-1}) (a completely positive map of C C^{*} -algebras) extends to a cochain map from the universal calculus on Mn(C) M_{n}(\mathbb{C} ) to the holomorphic ˉ \bar{\partial} calculus on CPn1 \mathbb{C} \mathbb{P}^{n-1} . The method uses connections on Hilbert C C^{*} -bimodules. This implies the existence of various functors, including one from Mn(C) M_{n}(\mathbb{C}) modules to holomorphic bundles on CPn1 \mathbb{C} \mathbb{P}^{n-1} .
