چکیده
These lectures present an elementary discussion of some background material relevant to the problem of de Sitter quantum gravity. The first two lectures discuss the classical geometry of de Sitter space and properties of quantum field theory on de Sitter space, especially the temperature and entropy of de Sitter space. The final lecture contains a pedagogical discussion of the appearance of the conformal group as an asymptotic symmetry group, which is central to the dS/CFT correspondence. A (previously lacking) derivation of asymptotically de Sitter boundary conditions is also given. Based on lectures by A. S. at the LXXVI Les Houches school “Unity from Duality: Gravity, Gauge Theory and Strings”, August 2001. On leave from the L. D. Landau Institute for Theoretical Physics, Moscow, Russia.

متن کاملHousehold food insecurity and diet diversity after the major 2010 landslide disaster in Eastern Uganda: a cross-sectional survey.
In 2010, a landslide in Bududa, Eastern Uganda, killed about 350 people and nearly 1000 affected households were resettled in Kiryandongo, Western Uganda. A cross-sectional survey assessed household food insecurity and diet diversity among 1078 affected and controls. In Bududa, the affected had a lower adjusted mean score of food insecurity than controls - 9·2 (se 0·4) v. 12·3 (se 0·4) (P<0·01)...
متن کاملar X iv : h ep - p h / 06 01 10 3 v 1 1 3 Ja n 20 06 A Quick Guide to SUSY Tools ∗
The last decade has seen the emergence of a wide range of automated calculations for supersymmetric extensions of the Standard Model. This guide contains a brief summary of these, with the main focus on hadron collider phenomenology, as well as a brief introduction to the so-called SUSY Les Houches Accord.
