Asymptotic behavior of non-autonomous fractional p-Laplacian equations driven by additive noise on unbounded domains

Bulletin of Mathematical Sciences, 2021
This paper deals with the asymptotic behavior of solutions to non-autonomous, fractional, stochastic p-Laplacian equations driven by additive white noise and random terms defined on the unbounded domain ℝN.

Lagrangians and integrability for additive fourth-order difference equations [PDF]

The European Physical Journal Plus, 2020
We use a recently found method to characterise all the invertible fourth-order difference equations linear in the extremal values based on the existence of a discrete Lagrangian. We also give some result on the integrability properties of the obtained family and we put it in relation with known classifications.

Stability of Equilibrium Points of Fractional Difference Equations with Stochastic Perturbations

Advances in Difference Equations, 2008
It is supposed that the fractional difference equation xn+1=(μ+∑j=0kajxn−j)/(λ+∑j=0kbjxn−j), n=0,1,…, has an equilibrium point x^ and is exposed to additive stochastic perturbations type of σ(xn−x^)ξn+1 that are ...

Intuitionistic fuzzy stability results of additive functional equation by two different approaches

Journal of Physics: Conference Series, 2021
Abstract In this current work, we examine the Hyers-Ulam(H-U) stability results for a finite variable additive functional equation (Ref.[6]) in Intuitionistic Fuzzy Normed space(IFN-space) is discussed by means of direct and fixed point methods.

Effect of comorbid mood and anxiety disorders on breast and cervical cancer screening in immune-mediated inflammatory disease.

PLoS ONE, 2021
We aimed to examine rates of breast and cervical cancer screening in women with immune-mediated inflammatory diseases (IMID), including inflammatory bowel disease (IBD), multiple sclerosis (MS) and rheumatoid arthritis (RA) versus a matched cohort with ...

Heterogeneous genetic (co)variances in simulated closed herds under selection - 10.4025/actascianimsci.v34i1.10934

Acta Scientiarum: Animal Sciences, 2011
Assuming that selection in closed herds can promote reduction in additive genetic variance, multiple regression models were used to estimate this change in additive genetic (co)variance component, over the years when the selection was done.
