What Baker-Gill-Solovay point to is the fact that certain simple diagonalising techniques do relativize, so pointing to the necessity for something more subtle from the theorist's tool bag.pmt6sbchttp://www.blogger.com/profile/17516781833165880822noreply@blogger.comtag:blogger.com,1999:blog-32371144.post-53646275578145752702013-01-13T23:30:21.571-05:002013-01-13T23:30:21.571-05:00RH is solved and done .RH is solved and done .Sunkhirous Yadegarhttp://www.blogger.com/profile/07351205729018789001noreply@blogger.comtag:blogger.com,1999:blog-32371144.post-32736161051137701952012-12-31T14:23:10.364-05:002012-12-31T14:23:10.364-05:00Thanks -- I was aware of his work on the Riemann H...Thanks -- I was aware of his work on the Riemann Hypothesis but didn't think it important enough to include on the list.

The pre-war record for the number of zeros located on the line was held by Ted Titchmarsh, confirming that the first 1041 points were OK. Turing extended this to the first 1104 zeros but then, unfortunately, the computer broke down. He devised what is now called “Turing’s method” for easier computational analysis of the function, detailed in his papers “A method for the calculation of the zeta-function” and “Some calculations of the Riemann zeta-function,” which are both widely referenced in modern mathematical publications.Alan Richmondhttp://www.blogger.com/profile/17383150571403817857noreply@blogger.com
