Next, we define the so-called &quot;extended alphabet&quot; or &quot;bundled alphabet&quot; E!A! as:

   E!A!  =  !A! |_| d!A!  =  {a_1, ..., a_n,  da_1, ..., da_n}.

This supplies enough material to construct the &quot;differential extension&quot; EA,
or the &quot;tangent bundle&quot; over the initial space A, in the following fashion:

   EA  =  A x dA  =  &lt;|E!A!|&gt;  =  &lt;|!A! |_| d!A!|&gt;

       =  &l
