Exponential and Power-Law Hierarchies from Supergravity
We examine how a d-dimensional mass hierarchy can be generated from a d+1-dimensional set up. We consider a d+1–dimensional scalar, the hierarchon, which has a potential as in gauged supergravities. We find that when it is in its minimum, there exist solutions of Hořava-Witten topology R × S/Z with domain walls at the fixed points and anti-de Sitter geometry in the bulk. We show that while stan...
متن کاملDiscrete power law with exponential cutoff and Lotka's Law
The first bibliometric law appeared in Alfred J. Lotka’s 1926 examination of author productivity in chemistry and physics. The result is that the productivity distribution is thought to be described by a power law. In this paper, Lotka’s original data on author productivity in chemistry is reconsidered by comparing the fit of the data to both a discrete power law and a discrete power law with e...
متن کاملHierarchies and textures in supergravity unification.
It is proposed that supergravity unified models contain in addition to the hidden and the visible sectors, a third sector which contains exotic matter with couplings to the fields of both the visible and the hidden sectors. After spontaneous breaking of supersymmetry exotic matter becomes superheavy and its elimination leads to quark-lepton textures at the GUT scale with a hierarchy in powers o...
متن کاملNew statistic for financial return distributions: power-law or exponential?
We introduce a new statistical tool (the TP-statistic and TE-statistic) designed specifically to compare the behavior of the sample tail of distributions with power-law and exponential tails as a function of the lower threshold u. One important property of these statistics is that they converge to zero for power laws or for exponentials correspondingly, regardless of the value of the exponent o...
متن کاملPower-law versus exponential distributions of animal group sizes.
There has been some confusion concerning the animal group size: an exponential distribution was deduced by maximizing the entropy; lognormal distributions were practically used; as power-law decay with exponent 3/2 was proposed in physical analogy to aerosol condensation. Here I show that the animal group-size distribution follows a power-law decay with exponent 1, and is truncated at a cut-off...
