"In mathematical optimization, linear-fractional programming (LFP) is a generalization of linear programming (LP). Whereas the objective function in a linear program is a linear function, the objective function in a linear-fractional program is a ratio of two linear functions. A linear program can be regarded as a special case of a linear-fractional program in which the denominator is the constant function one. " - Linear fractional function

NettetLet X be the quadric cone of dimension 2, defined by the equation xy = z 2 in affine 3-space over a field. Then the line D in X defined by x = z = 0 is not principal on X near the origin. Note that D can be defined as a set by one equation on X, namely x = 0; but the function x on X vanishes to order 2 along D, and so we only find that 2D is Cartier (as …
