D.12.5.5 monomialLcm
Procedure from library teachstd.lib (see teachstd_lib).
- Usage:
- monomialLcm(m,n); m,n of type poly or vector
- Return:
- least common multiple of leading monomials of m and n, of type poly
- Note:
- if m = (x1...xr)^(a1,...,ar)*gen(i) (gen(i)=1 if m is of type poly)
and n = (x1...xr)^(b1,...,br)*gen(j), then the proc returns
(x1,...,xr)^(max(a1,b1),...,max(ar,br)) if i=j and 0 if i!=j.
