Ultimate Boundedness and Finite Time Stability for a High Dimensional Fractional-Order Lorenz Model
Fractal and Fractional, 2022 In this paper, the global attractive set (GAS) and positive invariant set (PIS) of the five-dimensional Lorenz model with the fractional order derivative are studied.

On the Recursive Sequence xn+1=A+xnp/xn−1p
Discrete Dynamics in Nature and Society, 2007 This paper studies the boundedness, global attractivity, and periodicity of the positive solutions of the difference equation xn+1=A+xnp/xn−1p, n∈ℕ0, with p,A∈(0,∞).

Subadditive periodic functions [PDF]
Opuscula Mathematica, 2011 Some conditions under which any subadditive function is periodic are presented. It is shown that the boundedness from below in a neighborhood of a point of a subadditive periodic (s.p.) function implies its nonnegativity, and the boundedness from above ...

On the uniform boundedness of the solutions of systems of reaction-diffusion equations
Electronic Journal of Qualitative Theory of Differential Equations, 2005 We consider a system of reaction-diffusion equations for which the uniform boundedness of the solutions can not be derived by existing methods. The system may represent, in particular, an epidemic model describing the spread of an infection disease ...

Global boundedness of a class of multilinear Fourier integral operators
Forum 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 ...

Global well-posedness and Turing–Hopf bifurcation of prey-taxis systems with hunting cooperation
European Journal of Applied MathematicsThis paper is concerned with a predator–prey system with hunting cooperation and prey-taxis under homogeneous Neumann boundary conditions. We establish the existence of globally bounded solutions in two dimensions.

Global and local boundedness of Polish groups [PDF]
Indiana University Mathematics Journal, 2013 We present a comprehensive theory of boundedness properties for Polish groups developed with a main focus on Roelcke precompactness (precompactness of the lower uniformity) and Property (OB) (boundedness of all isometric actions on separable metric spaces). In particular, these properties are characterised by the orbit structure of isometric actions on

Stochastic Logistic Systems with Jumps
Journal of Applied Mathematics, 2014 This paper is concerned with a stochastic nonautonomous logistic model with jumps. In the model, the martingale and jump noise are taken into account. This model is new and more feasible and applicable.
