The trick is to find the groebner basis with various ordering of the variables ( all in lp ) and then use the necessary polynomials and get the answer kamlesh[/quote]

 Post subject: solving systems of polynomials with parameters(symbols)
 Hello , I have a system of polynomial equations in variables as well as in parameters . I want to solve it in variables ( in terms of a parameters and a chosen variable ) . Tried using the solve command after computing the grobner basis . It says the system has parameters and refused to solve it . Whereas the same problem was solved using mathematica .I need to do it using singular , can somebody tell me where am I wrong ?// The actual problem f1 = D + 2AC + A^2 + 2B - c = 0 ; f2 = A^2 + 2BD + 2ABC + B^2 - d = 0 ; f3 = B^2D - e =0 ;f4 = AD-BC = 0;with B,C,D,A as variables in lex ordr and c,d,e are parameters .mathematica gives a 6th deg polynomial in B with coeffs ( coming from the parameters ) , and other var expressed in terms of B and parameters . // Can anybody suggest other useful topics to look into for dealing with similar problems ?kamlesh Hello , I have a system of polynomial equations in variables as well as in parameters .
