Singular Manual: lpMis2Dim

| ##### 7.7.7.0. lpMis2Dim Procedure from library `fpadim.lib` (see fpadim_lib). Usage: lpMis2Dim(M); M an ideal Return: int, the K-dimension of the factor algebra Purpose: Computing the K-dimension out of given mistletoes Assume: - basering is a Letterplace ring. G is a Letterplace ideal. - M contains only monomials Note: - The mistletoes have to be ordered lexicographically -> OrdMisLex. Example:
    LIB "fpadim.lib";
    ring r = 0,(x,y),dp;
    def R = makeLetterplaceRing(5); // constructs a Letterplace ring
    setring R; // sets basering to Letterplace ring
    ideal L = x(1)*y(2),y(1)*x(2)*y(3);
    // ideal containing the mistletoes
    lpMis2Dim(L); // returns the K-dimension of the factor algebra
    ==> 6
