Abstract A set of data with positive values follows a Pareto distribution if the log–log plot of value versus rank is approximately a straight line. A Pareto distribution satisfies Zipf’s law if the log–log plot has a slope of $-1$. Since many types of ranked data follow Zipf’s law, it is considered a form of universality. We propose a mathematical explanation for this phenomenon based on Atlas models and first-order models, systems of strictly positive continuous semimartingales with…

TLDR
A checkpoint-based fast recovery strategy for the RDD cache that analyzes the task execution mechanism of the in-memory computing framework and forms a new failure recovery strategy using the failure recovery model plus weight information based on the semantic analysis of the code to improve the efficiency of the data recovery mechanism.

Generalized Pareto Curves: Theory and Applications
We define generalized Pareto curves as the curve of inverted Pareto coefficients b(p), where b(p) is the ratio between average income or wealth above rank p and the p-th quantile Q(p) (i.e. b(p) =
ON A CLASS OF SKEW DISTRIBUTION FUNCTIONS
It is the purpose of this paper to analyse a class of distribution functions that appears in a wide range of empirical data-particularly data describing sociological, biological and economic
A phase transition behavior for Brownian motions interacting through their ranks
Consider a time-varying collection of n points on the positive real axis, modeled as Exponentials of n Brownian motions whose drift vector at every time point is determined by the relative ranks of
Equilibrium Fluctuation of the Atlas Model
We study the fluctuation of the Atlas model, where a unit drift is assigned to the lowest ranked particle among a semi-infinite ($ \mathbb{Z}_+ $-indexed) system of otherwise independent Brownian
Zipf's Law for Cities: An Explanation
Zipf ’s law is a very tight constraint on the class of admissible models of local growth. It says that for most countries the size distribution of cities strikingly fits a power law: the number of

TLDR
In the letter, a new concept named nons asymmetric entropy was introduced, maximizing nonsymmetric entropy leads naturally to Zipf’s law.
Reflected Brownian motion with skew symmetric data in a polyhedral domain
SummaryThis paper is concerned with the characterization and invariant measures of certain reflected Brownian motions (RBM's) in polyhedral domains. The kind of RBM studied here behaves like
HYBRID ATLAS MODELS
We study Atlas-type models of equity markets with local characteristics that depend on both name and rank, and in ways that induce a stable capital distribution. Ergodic properties and rankings of
Reflected Brownian Motion on an Orthant
We consider a K-dimensional diffusion process Z whose state space is the nonnegative orthant. On the interior of the orthant, Z behaves like a Kdimensional Brownian motion with arbitrary covariance
Convergence rates for rank-based models with applications to portfolio theory
We determine rates of convergence of rank-based interacting diffusions and semimartingale reflecting Brownian motions to equilibrium. Bounds on fluctuations of additive functionals are obtained using
