On a Nonlinear Coupled Fractional Differential System With Multiderivative‐Terms and Coupled Closed Boundary Data

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This article is devoted to the study of existence, uniqueness, and Ulam–Hyers stability for a coupled system of two nonlinear Caputo‐type multiterm fractional differential equations equipped with coupled closed boundary data. The concept of coupled closed boundary conditions finds its applications in several physical situations, like composite panels ...

Supporting weakly Pareto optimal allocations in infinite dimensional nonconvex economies [PDF]

In this paper, we prove a new version of the Second Welfare Theorem for economies with a finite number of agents and an infinite number of commodities, when the preference correspondences are not convex-valued and/or when the total production set is not ...

Mixing for positive operators in Banach lattices

, 2003
In this paper we extend M. Lin's definition of mixing for positive contractions in L1(X,Σ,m) with m(X)=1 to positive operators in Banach lattices with weak-order units, and we generalize Lin's Theorem 2.1 (Z. Wahrsch. Verw.

A Note on Spectral Sublinearity for Collections of Positive Compact Operators on Banach Lattices

Special Matrices, 2018
In this paper we consider the question when a triangularizable semigroup S of positive compact ideal-triangularizable operators on an order continuous Banach lattice X is ideal-triangularizable.

Production Equilibria in Vector Lattices [PDF]

The general purpose of this paper is to prove quasiequilibrium existence theorems for production economies with general consumption sets in an infinite dimensional commodity space, without assuming any monotonicity of preferences or free-disposal in ...

Homogeneous orthogonally additive polynomials on Banach lattices

, 2006
The main result in this paper is a representation theorem for homogeneous orthogonally additive polynomials on Banach lattices. The representation theorem is used to study the linear span of the set of zeros of homogeneous real-valued orthogonally ...

Characterization of Banach Lattices in Terms of Quasi-Interior Points

International Journal of Mathematics and Mathematical Sciences, 2013
In terms of quasi-interior points, criteria that a Banach lattice has order continuous norm or is an -space with a unit are given. For example, if is Dedekind complete and has a weak order unit, then has order continuous norm if and only if the set of

Weak and almost Dunford–Pettis operators on Banach lattices

, 2013
We introduce the class of Banach lattices with the AM-compactness property and we use it to characterize Banach lattices on which each positive weak Dunford–Pettis operator is almost Dunford–Pettis and conversely.
