We give a complete description of the states of the C.C.R. algebra for a finite number of degrees of freedom which are invariant with respect to subgroups of the translation group of phase space. We make precise some well-known results of quantum mechanics such as Bloch theorem.

The law of international responsibility plays a fundamental role in the modern system of international law, surpassed by none and paralleled only by the law of treaties. The volume seeks to cover the entirety of the field of international responsibility, with a particular focus on the work of the International Law Commission. It provides detailed discussion and analysis of the historically predominant topics of State responsibility, on which the ILC completed its work in 2001, and the specific sub-topic of diplomatic protection, work on which was completed by the ILC in 2006. However, it also covers both the topic of responsibility of international organizations, on which the ILC's work is ongoing (a set of draft Articles having been adopted on first reading in 2009), and that of liability for harmful activities not prohibited under international law on which the ILC adopted drafts in 2001 and 2006.
