This talk aims to be an accessible introduction to the foundational work of Donaldson on projective embeddings and constant scalar curvature Kaehler metrics, often called “quantisation” in Kaehler geometry. After introducing various key objects related to the geometric quantisation, we shall see how the “quantised” metrics approximate Kaehler-Einstein (or more generally constant scalar curvature Kaehler) metrics in the “semiclassical” limit. We shall also discuss how this is used to numerically approximate Calabi-Yau metrics and its connection to Chow stability of the underlying manifold.
