Interconnection between Wick multiplication and integration on spaces of nonregular generalized functions in the Lévy white noise analysis

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2019
We deal with spaces of nonregular generalized functions in the Lévy white noise analysis, which are constructed using Lytvynov's generalization of a chaotic representation property.

Area‐restricted search under realistic constraints

open access: yesOikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

Persistence and extinction for stochastic logistic model with Levy noise and impulsive perturbation

open access: yesElectronic Journal of Differential Equations, 2015
This article investigates a stochastic logistic model with Levy noise and impulsive perturbation. In the model, the impulsive perturbation and Levy noise are taken into account simultaneously.

On Wick calculus on spaces of nonregular generalized functions of Levy white noise analysis

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2018
Development of a theory of test and generalized functions depending on infinitely many variables is an important and actual problem, which is stipulated by requirements of physics and mathematics.

Scaling turbulence drives the general circulation

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

The Averaging Principle for Caputo Type Fractional Stochastic Differential Equations with Lévy Noise

open access: yesFractal and Fractional
In this paper, the averaging principle for Caputo type fractional stochastic differential equations with Lévy noise is investigated with consideration of a new method for dealing with singular integrals.

Stochastic oscillations suppression by levy-noise [PDF]

open access: yesЖурнал нано- та електронної фізики, 2009
We consider effect of stochastic sources self-organization process being initiated with creation of the limit cycle. It is shown that stochastic system driven by stable Levy noise can not display oscillations in non-equilibrium steady state.

Does Carbon Intensity Affect the Cost of Equity? An Empirical Study From Mexico

open access: yesSustainable Development, EarlyView.
ABSTRACT Climate change poses significant risks for companies, particularly in emerging countries like Mexico, where sustainability perceptions are evolving. This study analyzes how carbon emissions affect the cost of equity capital (CoE) for Mexican firms.

LG–Holling type II diseased predator ecosystem with Lévy noise and white noise

open access: yesAdvances in Difference Equations, 2018
This paper considers an LG–Holling type II diseased predator ecosystem with Lévy noise and white noise. In this prey–predator system, assuming that the predator population is infected by disease and divided into two classes: susceptible predator and ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

open access: yesSustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...
