WE RECALL that a smooth algebraic variety defined over an algebraically closed field possesses a Zariski open which is a “good neighborhood”. a successive extension of incomplete curves [I]. We use this fact, together with the formalism of etale homotopy theory, to prove the following theorem:THEOREM 10. Let X be a pointed, smootfl variety otter an algebraically closed field k, let L be a finite set of primes excluding the characteristic of k, and let (); denote completion rvitfj respect to the class C, of finite I-groups for each I in L. Tfzere exists a pointed etale neighborhood U of X such that for all I in L
