TYP::IspA --
tests whether the argument is a product of generators of the
p-basis on a formal alphabet expression
Call(s)
TYP::IspA(expr)
Parametersexpr | - | any expression |
Introduction
The TYP::IspA function tests whether expr is a product of generators of
the p-basis on a formal alphabet expression, that is a product of power sum
symmetric functions 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 Ai's are the only formal variables in alphabets.
Example 1>> muEC::TYP::IspA( p[1](A1-A2) );
TRUE
>> muEC::TYP::IspA( p[3,3,1](k/3*A3) );
TRUE
