+      A.Asperti, discussing some basic notions of number theory, for
+      the stable version of Matita.</p>
+
+      <p>A <a href="docs/tutorial/igft.html">tutorial</a> by E.Tassi based on
+      the formalization of the paper "Between formal topology and game theory:
+      an explicit solution for the conditions for an inductive generation of
+      formal topologies" by S.Berardi and S.Valentini. The tutorial describes
+      the ng version of Matita (not officially released yet, cohexisting with
+      the stable system in version 0.5.8). If some characters are not displayed
