But assuming you have a working Isabelle 2016-1 distribution, it can be easily installed. The necessary theory files for Nominal2 can be downloaded from:<ul><li> <A HREF="http://nms.kcl.ac.uk/christian.urban/Publications/Nominal2-2016-1.tgz">Nominal2-2016-1.tgz</A> (19 April 2018) </li></ul>Unpack the tgz-file. This will create a directory Nominal and alsoNominal/Ex. If you change into the latter directory and load, for example,Lambda.thy, then you are already up and running. You can proceed with this theory as if it was a "normal" theory based on Main. <p>You can also be on the bleeding edge by downloading the sources from this Mercurial <A HREF="http://talisker.inf.kcl.ac.uk/cgi-bin/repos.cgi/nominal2/">Repository</A>.<h3>Nominal1 and Isabelle 2016</h3>Nominal1 is part of the current distribution and can be installedas explained <A HREF="http://isabelle.in.tum.de/download.html">here</A>.<h3>(Obsolete) Nominal2 and older Isabelle</h3><A HREF="http://nms.kcl.ac.uk/christian.urban/Publications/Nominal2-2011-1.tgz">Nominal2-2011-1.tgz</A> (17 Feb. 2012)<BR> <A HREF="http://nms.kcl.ac.uk/christian.urban/Publications/Nominal2-2012.tgz">Nominal2-2012.tgz</A> (15 May 2012)<BR><A HREF="http://nms.kcl.ac.uk/christian.urban/Publications/Nominal2-2013.tgz">Nominal2-2013.tgz</A> (19 February 2013)<BR><A HREF="http://nms.kcl.ac.uk/christian.urban/Publications/Nominal2-2013-1.tgz">Nominal2-2013-1.tgz</A> (18 October 2013)<BR><A HREF="http://nms.kcl.ac.uk/christian.urban/Publications/Nominal2-2013-2.tgz">Nominal2-2013-2.tgz</A> (15 December 2013)<BR><A HREF="http://nms.kcl.ac.uk/christian.urban/Publications/Nominal2-2014.tgz">Nominal2-2014.tgz</A> (9 September 2014)<BR><A HREF="http://nms.kcl.ac.uk/christian.urban/Publications/Nominal2-2015.tgz">Nominal2-2015.tgz</A> (9 July 2015)<BR><A HREF="http://nms.kcl.ac.uk/christian.urban/Publications/Nominal2-2016.tgz">Nominal2-2016.tgz</A> (19 March 2016)<BR> </body></html>
