muEC::SFA::Sf2SfA – from SYMF objects to SFA objects

Transform symmetric functions to symmetric functions of alphabets.

→ Examples

Call:

muEC::SFA::Sf2SfA(sf, <alphab>)

Parameters:

sf

any valid expression in SYMF

alphab

any alphabet

Related Functions:

Details:

The muEC::SFA::Sf2SfA function transforms any symmetric function of the muEC::SYMF package into an object of SFA for a specific alphabet (by default A1).

Valid bases for symmetric functions are e, h, p, s, m.

Allowed alphabet expressions are linear combinations of formal alphabets A1, A2, A3, .... For instance 3/2*A1 - A3 + 3/4 is valid.

The inverse function is SfA2Sf.

Example 1:

muEC::SFA::Sf2SfA( s[3,1]*p[2] - e[2,1] );

math

muEC::SFA::Sf2SfA( s[3,1]*p[2] - e[2,1], A2 );

math

muEC::SFA::Sf2SfA( s[2,2], 2*A3 );
