| Description | Let $M$ be a smooth manifold equipped with a conformal structure, $E[w]$ the space of densities with the the conformal weight $w$ and $D_{w,w+d}$ the space of differential operators from $E[w]$ to $E[w+d]$. Conformal quantization $Q$ is a right inverse of the principle symbol map on $D_{w,w+d}$ such that $Q$ is conformally invariant and exists for all $w$. This is known to exists for generic values of $d$. We give explicit formulae for $Q$ for all $d$ out of the set of critical weights. We provide a simple description of this set and conjecture its minimality. |
