7.7.8.0. baumslagSolitar
Procedure from library fpalgebras.lib (see fpalgebras_lib).

Usage:
baumslagSolitar(m,n,d[,IsGroup]); n an integer, m an integer, d an integer, IsGroup an optional integer

Return:
ring

Note:
- the ring contains the ideal I, which contains the required relations - in the group case: A = a^(-1), B = b^(-1)
- negativ input is only allowed in the group case!
- d gives a degreebound and must be >m,n

This is a family

Example:
 
LIB "fpalgebras.lib";
def R = baumslagSolitar(2,3,4); setring R;
I;
==> I[1]=-b(1)*a(2)*a(3)*a(4)+a(1)*a(2)*b(3)
==> I[2]=a(1)*A(2)-1
==> I[3]=b(1)*B(2)-1
==> I[4]=a(1)*A(2)-A(1)*a(2)
==> I[5]=b(1)*B(2)-B(1)*b(2)
