On the boundedness of globally F-split varieties

open access: yesMathematische Zeitschrift, 2023
AbstractThis paper proposes the use of F-split and globally F-regular conditions in the pursuit of BAB type results in positive characteristic. The main technical work comes in the form of a detailed study of threefold Mori fibre spaces over positive dimensional bases. As a consequence we prove the main theorem, which reduces birational boundedness for

Robust Adaptive Tracking Control for Nonlinearly Parameterized High-Order Systems With Unmatched Disturbances

open access: yesIEEE Access, 2023
The output tracking problem for a class of nonlinearly parameterized high-order uncertain systems with unmatched disturbances is studied. The developed robust adaptive control scheme is based on the combination of a decoupled backstepping control method ...

Global quantization of pseudo-differential operators on compact Lie groups, SU(2) and 3-sphere [PDF]

open access: yes, 2008
Global quantization of pseudo-differential operators on compact Lie groups is introduced relying on the representation theory of the group rather than on expressions in local coordinates.

Global boundedness to a 3D chemotaxis-Stokes system with porous medium cell diffusion and general sensitivity

open access: yesAdvances in Nonlinear Analysis, 2022
In this article, we will develop an analytical approach to construct the global bounded weak solutions to the initial-boundary value problem of a three-dimensional chemotaxis-Stokes system with porous medium cell diffusion Δnm\Delta {n}^{m} for m≥6563m ...

Logistic damping effect in chemotaxis models with density-suppressed motility

open access: yesAdvances in Nonlinear Analysis, 2022
This paper is concerned with a parabolic-elliptic chemotaxis model with density-suppressed motility and general logistic source in an n-dimensional smooth bounded domain with Neumann boundary conditions.

Longterm existence of solutions of a reaction diffusion system with non-local terms modeling an immune response—An interpretation-orientated proof

open access: yesPartial Differential Equations in Applied Mathematics, 2022
This paper shows the global existence and boundedness of solutions of a reaction diffusion system modeling liver infections. The existence proof is presented step by step and the focus lies on the interpretation of intermediate results in the context of ...

Dynamics of a rational system of difference equations in the plane [PDF]

open access: yes, 2010
We consider a rational system of first order difference equations in the plane with four parameters such that all fractions have a common denominator. We study, for the different values of the parameters, the global and local properties of the system. In

On the practical global uniform asymptotic stability of stochastic differential equations [PDF]

open access: yes, 2015
The method of Lyapunov functions is one of the most effective ones for the investigation of stability of dynamical systems, in particular, of stochastic differential systems.
