Author: Jean-Louis Krivine
Abstract: We show how to transform into programs the proofs in classical Analysis which use the existence of an ultrafilter on the integers. The method mixes the classical realizability introduced by the author, with the &#8220;forcing&#8221; of P. Cohen. The programs we obtain, use read [...]<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=chernikov.wordpress.com&blog=1601836&post=266&subd=chernikov&ref=&feed=1" />]]></description>

Author: Gavriel Segre
Recent theologies concerning God&#8217;s death after Auschwitz are mathematically formalized through a suitable temporalization of Goedel&#8217;s Ontological Proof.
