The emphasis is put on the very special correlations that this theory makes possible: they are forbidden by very general arguments based on realism and local causality. In fact, these correlations are completely impossible in any circumstance, except the v ...

... is an isometry of M , as in Theorem 1.2, then f is smooth and df (p)|∆p coincides with the differential of the blow up at p, restricted to ∆p . In other words, Theorem 1.2 states that every isometry f of M is determined by f (p) and by its blow-up at p. We complete the introduction with a problem. Q ...
