Does anyone know where to find this paper? Formule de trace en géométrie non-commutative et hypothèse de Riemann = Trace formula in noncommutative geometry and the Riemann hypothesis http://cat.inist.fr/?aModele=afficheN&cpsidt=2561461 The purchase link is broken there.. it gets stuck in an infinite page redirect loop. I found the journal homepage at http://www.elsevier.com/wps/find/journaldescription.cws_home/600301/description#description and the link to the table of contents points to http://www.elseviermathematics.com/ but this page is completely blank! What gives? I think the paper seems interesting because he contructs a Frobenius-Perron operator from a classical map whose eigenvalues are the riemann zeros.
