SFA::ToeA -- develops any symmetric function on the e-basis

Call(s)


SFA::ToeA(sfa <,alist>)

Parameters

sfa- any valid expression of SFA
alist- a list of alphabets

Introduction

The SFA::ToeA function analyses sfa and develops any symmetric function in sfa on the basis of e-polynomials.

One can develop only symmetric functions of which alphabets are given in the optional argument.

Example 1

>> muEC::SFA::ToeA( s[3,1](2*A1) );
              e[4](2 A1) - 2 e[3, 1](2 A1) + e[2, 1, 1](2 A1)
>> muEC::SFA::ToeA( s[3,1](2*A1)*m[2,1](A2^2), [ A2^2, A3 ] );
                                         2             2
                s[3, 1](2 A1) (e[2, 1](A2 ) - 3 e[3](A2 ))
>> muEC::SFA::ToeA( s[2]( p[4,3](2*A1) ) + q*m[2,1](A2^2),
         [ p[4,3](2*A1) ] );
                                                                  2
       e[1, 1](p[4, 3](2 A1)) - e[2](p[4, 3](2 A1)) + q m[2, 1](A2 )
