Resolvents for Convex Functions on Geodesic Spaces and Their Nonspreadingness [PDF]

open access: goldAxioms
The convex optimization problems have been considered by many researchers on geodesic spaces. In these problems, the resolvent operators play an important role.

Experiments and Modeling of a Compliant Wall Response to a Turbulent Boundary Layer with Dynamic Roughness Forcing

open access: yesFluids, 2021
The response of a compliant surface in a turbulent boundary layer forced by a dynamic roughness is studied using experiments and resolvent analysis. Water tunnel experiments are carried out at a friction Reynolds number of Reτ≈410, with flow and surface ...

Optimal eddy viscosity for resolvent-based models of coherent structures in turbulent jets [PDF]

open access: yes, 2021
Response modes computed via linear resolvent analysis of a turbulent mean-flow field have been shown to qualitatively capture characteristics of the observed turbulent coherent structures in both wall-bounded and free shear flows.

On two resolvent matrices of the truncated Hausdorff matrix moment problem

open access: yesVisnik Harkivsʹkogo Nacionalʹnogo Universitetu im. V.N. Karazina. Cepiâ Matematika, Prikladna Matematika i Mehanika, 2022
We consider the truncated Hausdorff matrix moment problem (THMM) in case of a finite number of even moments to be called non degenerate if two block Hankel matrices constructed via the moments are both positive definite matrices.

Study Strong Convergence and Acceleration of New Iteration Type Three – Step

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2023
The aim of this article, we define new iterative methods called three-step type in which Jungck resolvent CR-iteration and resolvent Jungck SP-iteration are discussed and study rate convergence and strong convergence in Banach space to reach the fixed ...

On some extensions of the A-model [PDF]

open access: yesOpuscula Mathematica, 2020
The A-model for finite rank singular perturbations of class \(\mathfrak{H}_{-m-2}\setminus\mathfrak{H}_{-m-1}\), \(m \in \mathbb{N}\), is considered from the perspective of boundary relations.

THE TWO-SIDED ESTIMATES OF THE FREDHOLM RADIUS AND COMPACTNESS CONDITIONS FOR THE OPERATOR ASSOCIATED WITH A SECOND-ORDER DIFFERENTIAL EQUATION

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2021
In this paper we consider the properties of the resolvent of a linear operator corresponding to a degenerate singular second-order differential equation with variable coefficients, considered in the Lebesgue space.

Iterative Sequences for a Finite Number of Resolvent Operators on Complete Geodesic Spaces

open access: yesAxioms, 2021
We consider Halpern’s and Mann’s types of iterative schemes to find a common minimizer of a finite number of proper lower semicontinuous convex functions defined on a complete geodesic space with curvature bounded above.
