Procedures:

7.10.3.1 lpNoetherian		check whether A/<LM(GB)> is (left/right) Noetherian
7.10.3.2 lpIsSemiPrime		check whether A/<LM(GB)> is semi-prime
7.10.3.3 lpIsPrime		check whether A/<LM(GB)> is prime
7.10.3.4 lpGkDim		compute the Gelfand Kirillov dimension of A/<GB>
7.10.3.5 lpGlDimBound		compute an upper bound for the global dimension of A/<GB>
7.10.3.6 lpSubstitute		substitute a variable with polynomials (ring homomorphism)
7.10.3.7 lpUfGraph		constructs the Ufnarovskij graph for <LM(GB)>
7.10.3.8 lpCalcSubstDegBound		utility for lpSubstitute
