Raiders of the lost spacetime
Spacetime as we know and love it is lost in most approaches to quantum gravity. For many of these approaches, as inchoate and incomplete as they may be, one of the main challenges is to relate what they take to be the fundamental non-spatiotemporal structure of the world back to the classical spacetime of GR. The present essay investigates how spacetime is lost and how it may be regained in one...
متن کاملRaiders of the Lost AdS
We demonstrate that under certain conditions a theory of conformal quantum mechanics will exhibit the symmetries of two halfVirasoro algebras. We further demonstrate the conditions under which these algebras combine to form a single Virasoro algebra, and comment on the connection between this result and the AdS2/CFT1 correspondence. e-mail address:[email protected]

Compared with previous competitions, our custom robots were much more reliable and the batteries lasted much longer. The strategic component of the s...
متن کاملDoes the Accountable Care Act Aim to Promote Quality, Health, and Control Costs or Has It Missed the Mark? ;Comment on “Health System Reform in the United States”
McDonough’s perspective on healthcare reform in the US provides a clear, coherent analysis of the mix of access and delivery reforms in the Affordable Care Act (ACA) aka Obamacare. As noted by McDonough, this major reform bill is designed to expand access for health coverage that includes both prevention and treatment benefits among uninsured Americans. Additionally, this legislation includes s...
متن کاملOn the Mark and Markaracter Tables of Finite Groups
Let G be a finite group and C(G) be the family of representative conjugacy classes of subgroups of G. The matrix whose H,K-entry is the number of fixed points of the set G/K under the action of H is called the table of marks of G where H,K run through all elements in C(G). Shinsaku Fujita for the first time introduced the term “markaracter” to discuss marks for permutation representati...
