SchurRings :: eVariable

eVariable -- Elementary symmetric functions in a Symmetric ring

Description

For a Symmetric ring R of dimension n, R.eVariable is a function which assigns to each index 1\leq i\leq n the i-th elementary symmetric function. If i is outside the given bounds, an error is returned.

i1 : R = symmetricRing(QQ,5,EHPVariables => (a,b,c));
i2 : R.eVariable 3

o2 = a
      3
