TYP::Ise
--
tests whether the argument is a product of generators of the
e-basis
TYP::Ise(expr)
expr | - | any expression |
The TYP::Ise
function tests whether expr
is a product of generators of
the e-basis that is a product of elementary symmetric functions.
The indexing vector must be a partition.
