Boundedness results for commutators with BMO functions via weighted estimates: a comprehensive approach [PDF]
Mathematische Annalen, 2019 We present a unified method to obtain unweighted and weighted estimates of linear and multilinear commutators with BMO functions, that is amenable to a plethora of operators and functional settings.

Combining effects ensuring boundedness in an attraction–repulsion chemotaxis model with production and consumption [PDF]
Zeitschrift für Angewandte Mathematik und Physik, 2022 This paper is framed in a series of studies on attraction–repulsion chemotaxis models combining different effects: nonlinear diffusion and sensitivities and logistic sources, for the dynamics of the cell density, and consumption and/or production impacts,

The boundedness of fractional integral operators in local and global mixed Morrey-type spaces [PDF]
Positivity (Dordrecht), 2021 In this paper, we introduce the local and global mixed Morrey-type spaces and show some properties. Besides, we investigate the boundedness of the fractional integral operators $$I_\alpha $$ I α in these spaces.

Boundedness for a nonlocal reaction chemotaxis model even in the attraction-dominated regime [PDF]
Differential and Integral Equations, 2020 This work deals with a parabolic chemotaxis model with nonlinear diffusion and nonlocal reaction source. The problem is formulated on the whole space and, depending on a specific interplay between the coefficients associated to such diffusion and ...

Electronic Research Archive, 2022 In this paper, we consider a predator-prey model with density-dependent prey-taxis and stage structure for the predator. We establish the existence of classical solutions with uniform-in-time bound in a one-dimensional case.

Dynamical behaviors of a k-order fuzzy difference equation
Open Mathematics, 2022 Difference equations are often used to create discrete mathematical models. In this paper, we mainly study the dynamical behaviors of positive solutions of a nonlinear fuzzy difference equation: xn+1=xnA+Bxn−k(n=0,1,2,…),{x}_{n+1}=\frac{{x}_{n}}{A+B{x}_ ...

On a two-species competitive predator-prey system with density-dependent diffusion
Mathematical Biosciences and Engineering, 2022 This paper deals with a two-species competitive predator-prey system with density-dependent diffusion, i.e., $ \begin{eqnarray*} \label{1a} \left\{ \begin{split}{} &u_t = \Delta (d_{1}(w)u)+\gamma_{1}uF_{1}(w)-uh_{1}(u)-\beta_{1}uv,&(x,t)\in ...
