The $\ell^s$-boundedness of a family of integral operators on UMD Banach function spaces

, 2018
We prove the $\ell^s$-boundedness of a family of integral operators with an operator-valued kernel on UMD Banach function spaces. This generalizes and simplifies earlier work by Gallarati, Veraar and the author, where the $\ell^s$-boundedness of this ...

Investigation of the global dynamics of two exponential-form difference equations systems

Electronic Research Archive, 2023
In this study, we investigate the boundedness, persistence of positive solutions, local and global stability of the unique positive equilibrium point and rate of convergence of positive solutions of the following difference equations systems of ...

Stability of a diffusive predator–prey model with modified Leslie–Gower and Holling-type II schemes and time-delay in two dimensions

Advances in Difference Equations, 2018
Our investigation deals with the stability and permanence of diffusive predator–prey model with modified Leslie–Gower and Holling-type II schemes and time-delay in two dimensions.

A Dynamically Consistent Nonstandard Difference Scheme for a Discrete-Time Immunogenic Tumors Model

Entropy, 2022
This manuscript deals with the qualitative study of certain properties of an immunogenic tumors model. Mainly, we obtain a dynamically consistent discrete-time immunogenic tumors model using a nonstandard difference scheme.

The uniform boundedness theorem and a boundedness principle

Annals of Pure and Applied Logic, 2012
Abstract We deal with a form of the uniform boundedness theorem (or the Banach–Steinhaus theorem) for topological vector spaces in Bishop’s constructive mathematics, and show that the form is equivalent to the boundedness principle BD-N , and hence holds not only in classical mathematics but also in intuitionistic mathematics and in constructive

Boundedness in a quasilinear two-species chemotaxis system with consumption of chemoattractant

Electronic Journal of Qualitative Theory of Differential Equations, 2019
This paper deals with a two-species chemotaxis system \begin{equation*} \begin{cases} u_t=\nabla\cdot(D_1(u)\nabla u)-\nabla\cdot(u\chi_1(w)\nabla w)+\mu_1 u(1-u-a_1v),\quad &x\in \Omega,\quad t>0,\\ v_t=\nabla\cdot(D_2(v)\nabla v)-\nabla\cdot(v\chi_2(w)\

Fourier multipliers in Banach function spaces with UMD concavifications

, 2017
We prove various extensions of the Coifman-Rubio de Francia-Semmes multiplier theorem to operator-valued multipliers on Banach function spaces. Our results involve a new boundedness condition on sets of operators which we call $\ell^{r}(\ell^{s ...

Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

Population Ecology, EarlyView.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.
