Mar 5, 2012 at 22:17 comment added Anonymous Granville--Sound's "pretentious perspective" is expounded upon in section 3 (Primes in Arithmetic Progressions, without L-functions) of this recent survey: dms.umontreal.ca/%7Eandrew/PDF/ItalySurvey.pdf

Mar 3, 2012 at 22:45 comment added Micah Milinovich @Denis: Thank you for the clarification.
Mar 3, 2012 at 20:17 comment added Denis Chaperon de Lauzières The proof of Friedlander and Iwaniec is in their sieve book, "Opera de cribro" (Chapter 24); however, it does use zeros of L-functions in addition to sieve methods.
Mar 3, 2012 at 19:11 comment added Micah Milinovich I believe that there are now two elementary proofs of Linnik's theorem (in the sense that they avoid zeros of L-functions), one due to Friedlander-Iwaniec and another due to Granville-Soundararajan. I do not think either proof has appeared, but I heard Andrew Granville give a talk on the subject.

Mar 3, 2012 at 13:01 comment added js21 As far as I know, no elementary proof of Linnik's theorem is known (although easier theorems as Siegel's have elementary proofs). In an other article of A.Granville, it is suggested that Selberg's formula has been proved in the range $X>q^A$ (as in Linnik's theorem) by J. Friedlander in "Selberg’s formula and Siegel’s zero. Recent progress in analytic number theory, Academic Press, London—New York, 1981, 15–23" . If the proof relies only on a sieve argument, there's some chance that it's elementary ; but I haven't been able to find the aforedmentioned article, so I don't know.
Mar 3, 2012 at 10:21 comment added GH from MO Note that $\epsilon=q^{-L}$ is admissible by Linnik's method, for $L>0$ a large effective constant, see Corollary 18.8 in Iwaniec-Kowalski: Analytic number theory. Of course it uses complex analysis very substantially.
Mar 3, 2012 at 9:35 comment added js21 @Igor Rivin : as quid said, without complex analysis, but I wanted to skip the debate on the relevance of this concept. @Terry Tao : indeed A. Granville gives informations (obtained by elementary means) on the behaviour of $\Psi(X,q,a)$ when $X$ goes to infinity, but effectivity with respect to $q$ is lost at each ocurrence of the words "for $X$ sufficiently large"
Mar 3, 2012 at 2:41 comment added Terry Tao You may find this paper of Granville relevant: ams.org/mathscinet-getitem?mr=1220462 (also available at dms.umontreal.ca/~andrew/PDF/PNTforaps.pdf )
Mar 3, 2012 at 0:54 comment added user9072 @Igor Rivin: Maybe I am missing something, but OP says "with the usual meaning of elementary in this context", so basically no complex analysis; which seems even more transparent as before complex analyis is mentioned expicitly as 'what not'.
Mar 2, 2012 at 22:30 comment added Igor Rivin What DO you mean by elementary here?
