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...

Harmonic weak Maass forms and periods II
In this paper we investigate the Fourier coefficients of harmonic Maass forms of negative half-integral weight. We relate the algebraicity of these...

On a Characterization of the Logarithmic Mean
In the present note we are interested in proving the counterpart of the (right-hand side of the) celebrated Hermite–Hadamard inequality for

Experts’ intuitive mathematical discourses about integration in complex analysis
Although complex analysis is part of the study programs of many mathematics undergraduates, little research has been done on how individuals...

A robust second-order low-rank BUG integrator based on the midpoint rule
Dynamical low-rank approximation has become a valuable tool to perform an on-the-fly model order reduction for prohibitively large matrix...

Commutator Formulas for Gradient Ricci Shrinkers and Their Application to Linear Stability of Gradient Ricci Shrinkers
In this paper we have found a number of commutator formulas between the weighted divergence, the weighted Laplacian, the weighted Lichnerowicz...

Existence of Solution of a Free Boundary Problem for Reaction–Diffusion Systems
In this paper, we prove the existence of a solution of a novel free boundary problem for reaction-diffusion systems describing growth of biological...
