How to construct the statistic network? An association network of herbaceous [PDF]
Network Biology, 2012 In present study I defined a new type of network, the statistic network. The statistic network is a weighted and non-deterministic network. In the statistic network, a connection value, i.e., connection weight, represents connection strength and ...

Remarks on the Gibbs measures for nonlinear dispersive equations [PDF]
, 2014 We show, by the means of several examples, how we can use Gibbs measures to construct global solutions to dispersive equations at low regularity. The construction relies on the Prokhorov compactness theorem combined with the Skorokhod convergence theorem.

A quantitative version of James's Compactness Theorem [PDF]
Proceedings of the Edinburgh Mathematical Society, 2010 We introduce two measures of weak non-compactness JaE and Ja that quantify, via distances, the idea of boundary that lies behind James's Compactness Theorem.

Gerrymandering and Compactness: Implementation Flexibility and Abuse
, 2018 The shape of an electoral district may suggest whether it was drawn with political motivations, or gerrymandered. For this reason, quantifying the shape of districts, in particular their compactness, is a key task in politics and civil rights.

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018 Similarly to Wiener index, hyper-Wiener index of a connected graph is a widely applied topological index measuring the compactness of the structure described by the given graph. Hyper-Wiener index is the sum of the distances plus the squares of distances

Fixed Point Theorem via Measure of Non-Compactness for a New Kind of Contractions
Vestnik St. Petersburg University, Mathematics, 2023 In this paper, we will use the notion of α-admissible mappings in Banach spaces, to introduce the concept of Tβ-contractive mappings and establish a fixed point theorem for this type of contractions. Our theorems generalize and improve many results in the literature.
