Note on the Rényi entropy of 2D perturbed fermions [PDF]
Physical Review D, 2019 In this paper we study the Renyi entropy of 2D massless free fermions perturbed by the $T\bar{T}$ term and the $J\bar{T}$ term at the first order perturbation.

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Properties, Bounds, and Estimation of Rényi Entropy in Consecutive k-out-of-n:G Systems
Journal of MathematicsThis study investigates the Renyi entropy properties of consecutive k-out-of-n:G systems. Initially, a formula for the Renyi entropy of the lifetime of a consecutive k-out-of-n:G system is derived, offering a thorough insight into its Renyi entropy ...

Interdiction Models and Heuristics for Graph Propagation
Networks, EarlyView.ABSTRACT Given a graph G=(V,E)$$ G=\left(V,E\right) $$ and a set S⊂V$$ S\subset V $$ of activated/infected nodes, we consider the problem of determining the set of c$$ c $$ nodes that minimizes the network propagation on the subgraph that results from the removal of those c$$ c $$ nodes. To measure network propagation, we assume that a node i$$ i $$ is

On Metric Choice in Dimension Reduction for Fréchet Regression
International Statistical Review, EarlyView.Summary Fréchet regression is becoming a mainstay in modern data analysis for analysing non‐traditional data types belonging to general metric spaces. This novel regression method is especially useful in the analysis of complex health data such as continuous monitoring and imaging data.

Minimum Rényi Entropy Portfolios
, 2018 Accounting for the non-normality of asset returns remains challenging in robust portfolio optimization. In this article, we tackle this problem by assessing the risk of the portfolio through the "amount of randomness" conveyed by its returns.

Particle number fluctuations, Rényi entropy, and symmetry-resolved entanglement entropy in a two-dimensional Fermi gas from multidimensional bosonization [PDF]
, 2019 We revisit the computation of particle number fluctuations and the R\'enyi entanglement entropy of a two-dimensional Fermi gas using multidimensional bosonization.

The richness, frequency and relatedness components of mate diversity and mate portfolios
New Phytologist, EarlyView.The effects of (a) equal and (b, c) unequal contributions to mate portfolios by 10 mates on (d) Hill‐number mate diversity profiles (see Eqn 1). Summary Sexual reproduction produces genetically diverse families, especially when individuals mate with multiple partners.

Is It Easier to Count Communities Than Find Them?
Random Structures &Algorithms, Volume 68, Issue 4, July 2026.ABSTRACT Random graph models with community structure have been studied extensively in the literature. For both the problems of detecting and recovering community structure, an interesting landscape of statistical and computational phase transitions has emerged. A natural unanswered question is: Might it be possible to infer properties of the community

Physical Review Research, 2020 We present a method for calculating Rényi entanglement entropies for fermionic field theories originating from microscopic Hamiltonians. The method builds on an operator identity, which leads to the representation of traces of operator products, and thus
