NCo.BNR
The normal remainder of a polynomial with respect to a LIST of polynomials in a free monoid ring over the binary field F_{2}={0,1}.
Syntax
NCo.BNR(F:LIST, G:LIST):INT
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 ring environment alphabet (or set of indeterminates) X and word ordering via the functions NCo.SetX and NCo.SetOrdering, respectively, before calling this function. The default ordering is the length-lexicographic ordering ("LLEX"). For more information, please check the relevant functions.
@param F: a polynomial in the free monoid ring F_{2}<X>. Each polynomial is represented as a LIST of words (or terms) in <X>. 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 is represented as F:=["xy", "y", ""]. The zero polynomial 0 is represented as the empty LIST [].
@param G: a LIST of polynomials in the free monoid ring F_{2}<X>.
@return: a LIST which represents the normal remainder of F with respect to G.
Example
NCo.SetX(<quotes>xyXY</quotes>); NCo.SetOrdering(<quotes>LLEX</quotes>); F1:=[<quotes>xX</quotes>,<quotes></quotes>]; F2:=[<quotes>Xx</quotes>,<quotes></quotes>]; F3:=[<quotes>yY</quotes>,<quotes></quotes>]; F4:=[<quotes>Yy</quotes>,<quotes></quotes>]; G:=[F1,F2,F3,F4]; F:=[<quotes>xyYxxXYY</quotes>]; NCo.BNR(F,G); [<quotes>xxYY</quotes>] -------------------------------
