The Einstein-Vlasov sytem/Kinetic theory [PDF]
, 2002 The main purpose of this article is to guide the reader to theorems on global properties of solutions to the Einstein-Vlasov system. This system couples Einstein's equations to a kinetic matter model.

Fisheries Oceanography, Volume 34, Issue 1, January 2025.Abstract Understanding how ecosystem change influences fishery resources through trophic pathways is a key tenet of ecosystem‐based fishery management. System models (SM), which use numerical modeling to describe physical and biological processes, can advance inclusion of ecosystem and prey information in fisheries management; however, incorporating ...

Global pointwise decay estimates for defocusing radial nonlinear wave equations
, 2009 We prove global pointwise decay estimates for a class of defocusing semilinear wave equations in $n=3$ dimensions restricted to spherical symmetry. The technique is based on a conformal transformation and a suitable choice of the mapping adjusted to the ...

Symmetric hyperbolic systems for a large class of fields in arbitrary dimension [PDF]
, 2006 Symmetric hyperbolic systems of equations are explicitly constructed for a general class of tensor fields by considering their structure as r-fold forms. The hyperbolizations depend on 2r-1 arbitrary timelike vectors.

Put–Call Parities, absence of arbitrage opportunities, and nonlinear pricing rules
Mathematical Finance, Volume 34, Issue 4, Page 1242-1262, October 2024.Abstract When prices of assets traded in a financial market are determined by nonlinear pricing rules, different parities between call and put options have been considered. We show that, under monotonicity, parities between call and put options and discount certificates characterize ambiguity‐sensitive (Choquet and/or Šipoš) pricing rules, that is ...

Quantitative approximation by nonlinear convolution operators of Landau-Choquet type
, 2020 By using the concept of Choquet nonlinear integral with respect to a monotone set function, we introduce the nonlinear convolution operators of Landau-Choquet type, with respect to a family of submodular set functions.

A systematic review of multidimensional relevance estimation in information retrieval
WIREs Data Mining and Knowledge Discovery, Volume 14, Issue 5, September/October 2024.Aim of the systematic review and main findings. Abstract In information retrieval, relevance is perceived as a multidimensional and dynamic concept influenced by user, task, and domain factors. Relying on this perspective, researchers have introduced multidimensional relevance models addressing diverse search tasks across numerous knowledge domains ...

Large data decay of Yang-Mills-Higgs fields on Minkowski and de Sitter spacetimes
, 2019 We extend Eardley and Moncrief's $L^\infty$ estimates for the conformally invariant Yang-Mills-Higgs equations to the Einstein cylinder. Our method is to first work on Minkowski space and localise their estimates, and then carry them to the Einstein ...

Displacement sensing based on microscopic vision with high resolution and large measuring range
Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 18, Page 2840-2858, 15 September 2024.Abstract Microimage strain sensing (MISS) is a novel piston‐type sensor based on microscopic vision. In this study, optical disc slice is used as information carriers to improve MISS. There are multiple pits on the surface of an optical disc. By using machine vision algorithms, the pits can be converted into digital information, making them scales for ...

Robust distortion risk measures
Mathematical Finance, Volume 34, Issue 3, Page 774-818, July 2024.Abstract The robustness of risk measures to changes in underlying loss distributions (distributional uncertainty) is of crucial importance in making well‐informed decisions. In this paper, we quantify, for the class of distortion risk measures with an absolutely continuous distortion function, its robustness to distributional uncertainty by deriving ...
