NC.MRIsHomog

Checks whether a polynomial or a set (LIST) of polynomials is homogeneous in a finitely presented monoid ring.
Syntax
          
NC.MRIsHomog(X:STRING, Ordering:STRING, Relations:LIST, F:LIST):BOOL

          

Description
Please note: The function(s) explained on this page is/are using the ApCoCoAServer. You will have to start the ApCoCoAServer in order to use it/them.

Please set coefficient field via the function NC.SetFp (or NC.UnsetFp) before calling this function. The default coefficient field is Q. For more information, please check the relevant function.

Example
X := "xy"; 
Ordering:="LLEX"; 
Relations := []; 
F1 := [[1,"x"], [1,"y"]]; 
F2 := [[1,"xx"],[1,"xy"],[1,"x"]]; 
F := [F1,F2]; 
NC.MRIsHomog(X, Ordering, Relations, F);
False
-------------------------------
NC.MRIsHomog(X, Ordering, Relations, F1);
True
-------------------------------
NC.MRIsHomog(X, Ordering, Relations, F2);
False
-------------------------------
