A Uniform Boundedness Theorem [PDF]
Proceedings of the American Mathematical Society, 1967 A variation on the uniform boundedness theorem [2, p. 105] of functional analysis is obtained by replacing pointwise boundedness by a slightly stronger type of boundedness. This makes it possible to remove the category requirements from the set over which it is desired to have a collection of functions uniformly bounded.

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 ...

Journal of Nonlinear Mathematical Physics, 2021 The general fractional calculus becomes popular in continuous time random walk recently. However, the boundedness condition of the general fractional integral is one of the fundamental problems. It wasn’t given yet.

Sum of some product-type operators from mixed-norm spaces to weighted-type spaces on the unit ball
AIMS Mathematics, 2022 Let $ u_{j} $ be the holomorphic functions on the open unit ball $ \mathbb{B} $ in $ \mathbb{C}^{n} $, $ j = \overline{0, m} $, $ \varphi $ a holomorphic self-map of $ \mathbb{B} $, and $ \Re^{j} $ the $ j $th iterated radial derivative operator. In this

On the global attractivity and the periodic character of a recursive sequence [PDF]
Opuscula Mathematica, 2010 In this paper we investigate the global convergence result, boundedness, and periodicity of solutions of the recursive sequence \[x_{n+1} = ax_n + \frac{bx_{n-1}+cx_{n+2}}{dx_{n-1}+ex_{n+2}}, \quad n=0,1,\ldots,\] where the parameters \(a\), \(b\), \(c\),

Adaptive iterative learning control with trajectory shift
Xi'an Gongcheng Daxue xuebao, 2022 In order to solve the problem of trajectory shift in iterative learning control, an adaptive iterative learning control strategy was proposed. For linear time-varying systems with unknown parameters, an adaptive parameter updating algorithm was ...

Local Boundedness and Harnack Inequality for Solutions of Linear Nonuniformly Elliptic Equations [PDF]
Communications on Pure and Applied Mathematics, 2019 We study local regularity properties for solutions of linear, nonuniformly elliptic equations. Assuming certain integrability conditions on the coefficient field, we prove local boundedness and Harnack inequality.

Singularities of linear systems and boundedness of Fano varieties [PDF]
Annals of Mathematics, 2016 We study log canonical thresholds (also called global log canonical threshold or $\alpha$-invariant) of $\mathbb{R}$-linear systems. We prove existence of positive lower bounds in different settings, in particular, proving a conjecture of Ambro.
