The article deals with a famous representation of Otto III in apotheosis together with the monk Liuthar, responsible for the execution of the beautiful Gospels-book, donated to the Aachen Chapel ca. 996. It opens with a methodological discussion of modern approaches to medieval art, and especially the applicability of the post-medieval notion of “space”, that the author proposes to substitute for “places” and “plans”. Operating with these notions, he gives a minute description of the miniature on two opposite pages as an unseparable, meaningful unity, where places, plans, figures, gestures are full of sens. This analysis allows to review some stereotyped interpretations of the main scene, especially the “exemplary” one by Ernst Kantorowicz, who claimed it to be at the origin of the much later theory of the king’s two bodies.
In 2006, Russia amended its competition law and added the concepts of ‘collective dominance’ and its abuse. This was seen as an attempt to address the common problem of ‘conscious parallelism’ among firms in concentrated industries. Critics feared that the enforcement of this provision would become tantamount to government regulation of prices. In this paper we examine the enforcement experience to date, looking especially closely at sanctions imposed on firms in the oil industry. Some difficulties and complications experienced in enforcement are analysed, and some alternative strategies for addressing anticompetitive behaviour in concentrated industries discussed.
Let G be a semisimple algebraic group whose decomposition into the product of simple components does not contain simple groups of type A, and P⊆G be a parabolic subgroup. Extending the results of Popov , we enumerate all triples (G, P, n) such that (a) there exists an open G-orbit on the multiple flag variety G/P × G/P × . . . × G/P (n factors), (b) the number of G-orbits on the multiple flag variety is finite.
