FUNCTION: TohA - develop any symmetric function on the h-basis

CALLING SEQUENCE:

TohA(sfa)

TohA(sfa, alist)

SFA[TohA](sfa)

SFA[TohA](sfa, alist)

PARAMETERS:

sfa = any valid expression in SFA

alist = a list of alphabets

SYNOPSIS:

• The TohA function analyses sfa and develops any symmetric function in SFA on the linear basis of product of complete symmetric functions.

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

• Whenever there is a conflict between the function name TohA and another name used in the same session, use the long form SFA['TohA'].

EXAMPLES:

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