Almost Invertible Operators
This paper aims to provide a thorough characterization of the family of all Cantor-Bendixson derivatives of the spectrum, Browder spectrum, and the...

On a weighted Hermite–Hadamard inequality involving convex functional arguments
In this paper, we are interested in investigating a weighted variant of Hermite–Hadamard type inequalities involving convex functionals. The approach...

Integral Radial
m -Bakry–Émery Ricci Curvatures, Riccati Inequalities, and Ambrose-type TheoremsInspired by a recent work due to J.-Y. Wu (Potential Anal 58:203–223, 2023), we prove several new compactness criteria for complete Riemannian...

AN ECO-EPIDEMIOLOGICAL MODEL WITH NON-CONSUMPTIVE PREDATION RISK AND A FATAL DISEASE IN PREY
Apart from direct killing, the non-consumptive risk of the predation process influences the community dynamics of ecological systems. Recent studies...

Some aspects of k-ideals of semirings
The aim of this paper is to study some distinguished classes of k -ideals of semirings, which include k -prime, k -semiprime, k -radical, k -irreducible,...

A moment approach for entropy solutions of parameter-dependent hyperbolic conservation laws
We propose a numerical method to solve parameter-dependent scalar hyperbolic partial differential equations (PDEs) with a moment approach, based on a...

Some numerical radius bounds
In this paper, we first give two new upper bounds for the numerical radius of the product of two Hilbert space operators. The obtained bounds are...

Cardinality and IOD-type continuity of pullback attractors for random nonlocal equations on unbounded domains
We study the continuity set (the set of all continuous points) of pullback random attractors from a parametric space into the space of all compact...

New eigenvalue pinching results for Euclidean domains
We prove stability results associated with sharp eigenvalue upper bounds for several operators on embedded hypersurfaces and boundary problems on...

Lattice properties of strength functions
This paper investigates an important functional representation of the cone of bounded positive semidefinite operators. It is known that the...

Generalized Hamiltonian systems on subvarieties: constant rank case
For the constraint variety in symplectic manifold, the solvable Hamiltonian vector fields on the constraint are investigated. According to P.A.M....

Influence of Numerical Diffusion on the Growth Rate of Viscous Fingers in the Numerical Implementation of the Peaceman Model by the Finite Volume Method
A numerical model of oil displacement by a mixture of water and polymer based on the Peaceman model is considered. Numerical experiments were carried...
