Quantization on symplectic manifolds<br />

<strong>Bergman</strong> <strong>kernel</strong> <strong>and</strong> qeometric <strong>quantization</strong><br />

Guillemin-Sternberg conjecture II<br />

<strong>Geometric</strong> <strong>quantization</strong><br />

Quantization commutes <strong>with</strong> reduction<br />

Non-compact case : Vergne’s conjecture<br />

◮ When G is abelian, Meinrenken (JAMS 1996) <strong>and</strong><br />

Vergne (DMJ 1996).<br />

◮ General G, Meinrenken, Meinrenken-Sjamaar,<br />

technique of symplectic cut of Lerman, 1998<br />

Yonglian Tian - <strong>Weiping</strong> Zhang,<br />

Pure analytic approach, 1998, work for a general<br />

vector bundle E verifying certain positivity condition.<br />

For manifolds <strong>with</strong> boundary, etc.<br />

◮ Other proofs : Duistermaart-Guillemin-Meinrenken-Wu<br />

(for circle actions) <strong>and</strong> Jeffrey-Kirwan (for non-abelian<br />

group actions <strong>with</strong> certain extra conditions)<br />

Paradan, using the transversal index theory, 2001.<br />
