TYP::IssA
--
tests whether the argument is a generator of the s-basis on a
formal alphabet expression
TYP::IssA(expr)
expr | - | any expression |
The TYP::IssA
function tests whether expr
is a generator of
the s-basis on a formal alphabet expression, that is a Schur
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.
