Prohibiting Restriction of Free Trade within the Community: Articles 30-36 of the EEC Treaty

The problem of accommodating the tensions of power between the European Economic Community and individual Member States is particularly acute in the area of prohibitions on restriction on free trade within the Community. Professor van Themaat and Mr. Gormley analyze key aspects of this problem in select decisions of the Court of Justice concerning Articles 30-36 of the EEC Treaty. The areas of discussion include the extent to which Articles 30-36 affect internal economic regulations of Member States, the difference between trading within an established Community organization and trade in an area where no organization exists, and the relation of Articles 30-36 to other provisions of the Treaty. The authors conclude with a consideration of the prospects for federalization within the Common Market in light of the cases discussed earlier

Inversive Meadows and Divisive Meadows

Inversive meadows are commutative rings with a multiplicative identity element and a total multiplicative inverse operation whose value at 0 is 0. Divisive meadows are inversive meadows with the multiplicative inverse operation replaced by a division operation. We give finite equational specifications of the class of all inversive meadows and the class of all divisive meadows. It depends on the angle from which they are viewed whether inversive meadows or divisive meadows must be considered more basic. We show that inversive and divisive meadows of rational numbers can be obtained as initial algebras of finite equational specifications. In the spirit of Peacock's arithmetical algebra, we study variants of inversive and divisive meadows without an additive identity element and/or an additive inverse operation. We propose simple constructions of variants of inversive and divisive meadows with a partial multiplicative inverse or division operation from inversive and divisive meadows. Divisive meadows are more basic if these variants are considered as well. We give a simple account of how mathematicians deal with 1 / 0, in which meadows and a customary convention among mathematicians play prominent parts, and we make plausible that a convincing account, starting from the popular computer science viewpoint that 1 / 0 is undefined, by means of some logic of partial functions is not attainable.Comment: 18 pages; error corrected; 29 pages, combined with arXiv:0909.2088 [math.RA] and arXiv:0909.5271 [math.RA
