The Global Solutions and Moment Boundedness of Stochastic Multipantograph Equations [PDF]

open access: yesJournal of Control Science and Engineering, 2016
We consider the existence of global solutions and their moment boundedness for stochastic multipantograph equations. By the idea of Lyapunov function, we impose some polynomial growth conditions on the coefficients of the equation which enables us to ...

Global boundedness of a class of multilinear Fourier integral operators

open access: yesForum of Mathematics, Sigma, 2021
We establish the global regularity of multilinear Fourier integral operators that are associated to nonlinear wave equations on products of $L^p$ spaces by proving endpoint boundedness on suitable product spaces containing combinations of the local ...

Boundedness and Global Attractivity of a Higher-Order Nonlinear Difference Equation [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2010
We investigate the local stability, prime period-two solutions, boundedness, invariant intervals, and global attractivity of all positive solutions of the following difference equation: 𝑦𝑛+1=(𝑟+𝑝𝑦𝑛+𝑦𝑛−𝑘)/(𝑞𝑦𝑛+𝑦𝑛−𝑘), 𝑛∈ℕ0, where the parameters 𝑝,𝑞,𝑟∈(0,∞

Generalised theory on asymptotic stability and boundedness of stochastic functional differential equations [PDF]

open access: yes, 2011
Asymptotic stability and boundedness have been two of most popular topics in the study of stochastic functional differential equations (SFDEs) (see e.g. Appleby and Reynolds (2008), Appleby and Rodkina (2009), Basin and Rodkina (2008), Khasminskii (1980),
