In the case that the field is algebraically closed (say, the complex numbers), every maximal ideal corresponds to a point in "n"-space, by the nullstellensatz (the maximal ideal generated by formula_107 corresponds to the point formula_108). These representations of formula_109 are then parametrized by the dual space formula_110 the covector being given by sending each formula_105 to the corresponding formula_112. Thus a representation of formula_113 ("K"-linear maps formula_114) is given by a set of "n" numbers, or equivalently a covector formula_115
