TYP::IsmA
--
tests whether the argument is a generator of the m-basis on a
formal alphabet expression
TYP::IsmA(expr)
expr | - | any expression |
The TYP::IsmA
function tests whether expr
is a generator of
the m-basis on a formal alphabet expression, that is a monomial
symmetric function on a given alphabet.
The indexing vector must be a partition.
The alphabet can be for instance a polynomial in A1, A2, ...
.
Note that the A
i's are the only formal variables in alphabets.

>> muEC::TYP::IsmA( m[3,3,1](k/3*A3) );
