Global Boundedness of an Alarm–Taxis System With Nonlinear Diffusion

Mathematical Methods in the Applied Sciences
ABSTRACTIn this paper, we study an alarm–taxis system with nonlinear diffusion  . We consider this problem in a bounded domain   with Neumann boundary conditions. By the complex coupling energy estimates based on the Neumann semigroup smoothing properties, we establish the existence of globally bounded weak solutions for any  .

Global Boundedness of Solutions of Continuous Social Stratification Model

2021
We consider the continuous social stratification model in the special case when the influence of negative factors is uniformly spread among the society. We first obtain spatially homogeneous solutions of the problem. Next we employ the comparison theorems for nonlinear parabolic equations to derive sufficient conditions of global boundedness and blow ...

Global boundedness of solutions to a reaction-diffusion system

Mathematical Methods in the Applied Sciences, 1999
Summary: We obtain the global boundedness of solutions to a Fujita-type reaction-diffusion system of the type \[ u_t- d_1\Delta u= b_1 u^{p_1} v^{q_1},\quad v_t- d_2\Delta v= b_2 u^{p_2} v^{q_2},\quad (x,t)\in\Omega\times \mathbb{R}_+. \] This global boundedness results from diffusion effect, homogeneous Dirichlet boundary value conditions and ...

Robust Adaptive Control Revisited: Semi-global Boundedness and Margins

2010
While stability of adaptive control systems and their robustness to disturbances, unmodeled dynamics, and time-delays have been extensively analyzed in the literature, what is missing is the development of quantifiable margins that explicitly define the extent of these perturbations that the adaptive controller can withstand.

Liapunov functions and boundedness and global existence of solutions

Applicable Analysis, 1972
In this paper the properties of a Liapunov function and its derivatives are combined in obtaining sufficient conditions for the boundedness and global existence of solutions of the system of differential equations x=f(t,x) (1) where f: [0,∞)XRn→ Rn is continuous.
