Instability of thick brane worlds
We examined 5d thick brane worlds constructed by a real scalar field. The solutions are obtained in terms of a simple form of smooth warp factor. For the case of dS brane, we found a disease of the solutions. For example, it is impossible to construct thick-brane worlds with our simple smoothing. This result is independent of supersymmetry or other symmetries. [email protected] yahiro@s...
متن کاملPossible Worlds II: Nonreductive Theories of Possible Worlds
I briefly discussed a view (see (Lewis, 1986)) which attempts to use (SC) to provide a theory of possible worlds aimed at using (SC) to reduce modality. This review sets aside such reductive theories of possible worlds, and concentrates instead on four leading nonreductive theories. Though some of these theories have reductive variants, the versions that figure most prominently in contemporary ...
متن کاملThe Basis Problem in Many-worlds Theories *
It is emphasized that a many-worlds interpretation of quantum theory exists only to the extent that the associated basis problem is solved. The core basis problem is that the robust enduring states specified by environmental decoherence effects are essentially Gaussian wave packets that form continua of non-orthogonal states. Hence they are not a discrete set of orthogonal basis states to which...
متن کاملComplex structures in generalized small worlds.
We propose a generalization of small world networks, in which the reconnection of links is governed by a function that depends on the distance between the elements to be linked. An adequate choice of this function lets us control the clusterization of the system. Control of the clusterization, in turn, allows the generation of a wide variety of topologies.
متن کاملGeneralized probabilities in statistical theories
In this review article we present different formal frameworks for the description of generalized probabilities in statistical theories. We discuss the particular cases of probabilities appearing in classical and quantum mechanics, possible generalizations of the approaches of A. N. Kolmogorov and R. T. Cox to non-commutative models, and the approach to generalized probabilities based on convex ...
