(Standard) degree of a polynomial in a free monoid ring over
F2.
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 ring environment
alphabet (or set of indeterminates)
X and
admissible ordering via the functions
NC.SetX and
NC.SetOrdering, respectively, before calling the function. The default ordering is length-lexicographic ordering ("LLEX"). For more information, please check the relevant functions.
- @param F: a polynomial in the free monoid ring F2. Each polynomial is represented as a LIST of words (or terms) in . Each word is represented as a STRING. For example, xy^2x is represented as "xyyx", and the identity is represented as the empty string "". Thus, the polynomial F=xy-y+1 in F2 is represented as F:=["xy", "y", ""]. The zero polynomial 0 is represented as the empty LIST [].
- @return: a INT which represents the (standard) degree of F. If F=0, the function returns 0.

NC.SetOrdering("LLEX");
