Convergence of generalized MIT bag models to Dirac operators with zigzag boundary conditions
This work addresses the resolvent convergence of generalized MIT bag operators to Dirac operators with zigzag type boundary conditions. We prove that...

Topological phase estimation method for reparameterized periodic functions
We consider a signal composed of several periods of a periodic function, of which we observe a noisy reparametrization. The phase estimation problem...

An adaptive finite element DtN method for the acoustic-elastic interaction problem
Consider the scattering of a time-harmonic acoustic incident wave by a bounded, penetrable and isotropic elastic solid, which is immersed in a...

Estimates for coefficients in Jacobi series for functions with limited regularity by fractional calculus
In this paper, optimal estimates on the decaying rates of Jacobi expansion coefficients are obtained by fractional calculus for functions with...

Deformations and q-Convolutions. Old and New Results
This paper is the survey of some of our results related to q -deformations of the Fock spaces and related to q -convolutions for probability measures...

On a class of Kirchhoff problems with nonlocal terms and logarithmic nonlinearity
In this present paper, we concern investigating nonlinear Kirchhoff-type problems subject to Dirichlet boundary conditions, incorporating nonlocal...

Additive manufacturing-driven topological design considering overhang and connectivity constraints induced by closed cavity
Closed cavity is a common design feature in topology optimization, but quite unfavorable for fabrication, even for highly flexible powder-based...

Well-posedness for a class of pseudo-differential hyperbolic equations on the torus
In this paper we establish the well-posedness of the Cauchy problem for a class of pseudo-differential hyperbolic equations on the torus. The class...

Uniform-in-mass global existence for 4D Dirac–Klein–Gordon equations
We are interested in four-dimensional Dirac–Klein–Gordon equations, a fundamental model in particle physics. The main goal of this paper is to...

An elementary proof of existence and uniqueness for the Euler flow in localized Yudovich spaces
We revisit Yudovich’s well-posedness result for the 2-dimensional Euler equations for an inviscid incompressible fluid on either a sufficiently...

Open problem on the maximum exponential augmented Zagreb index of unicyclic graphs
A topological index is a numerical property of a molecular graph that explains structural features of molecules. The potential of topological indices...

Local and global strong solutions to the 3D Navier–Stokes equations with dam**
This paper studies regularity properties of the weak solutions to the 3D Navier–Stokes equations with dam** in the whole space and bounded domains....

Trending on the use of Google mobility data in COVID-19 mathematical models
Google mobility data has been widely used in COVID-19 mathematical modeling to understand disease transmission dynamics. This review examines the...

Common fixed points of a pair of \((\psi ,\phi )\)-weakly contractive maps via ceiling distance with applications
In this paper, we discuss a critical analysis of a paper by Kumar (J Comput Appl Math 404:1–16 2022), found some corrections through the use of...

Stability via closure relations with applications to dissipative and port-Hamiltonian systems
We consider differential operators A that can be represented by means of a so-called closure relation in terms of a simpler operator
