Silver mean conjectures for 15-d volumes and 14-d hyperareas of the separable two-qubit systems

, 2004
Extensive numerical integration results lead us to conjecture that the silver mean, that is, s = \sqrt{2}-1 = .414214 plays a fundamental role in certain geometries (those given by monotone metrics) imposable on the 15-dimensional convex set of two-qubit

Set-point Regulation of Constrained Strongly Monotone Systems

IFAC Proceedings Volumes, 2011
Abstract To date, monotone systems have been basically studied from the analysis viewpoint, whereas control design issues for such dynamical systems have not been considerably remarked. This paper focuses on set-point regulation of output of strongly monotone systems using a static output feedback under input constraints.

Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

Advanced Engineering Materials, EarlyView.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

Algorithms for Solving the Resolvent of the Sum of Two Maximal Monotone Operators with a Finite Family of Nonexpansive Operators

Axioms
In this paper, we address a variational problem involving the sum of two maximal monotone operators combined with a finite family of nonexpansive operators. To solve this problem, we propose iterative algorithms based on single-valued mappings. First, we

Strong Convergence Theorems for Solutions of Equations of Hammerstein Type

Journal of Applied Mathematics, 2013
We consider an auxiliary operator, defined in a real Hilbert space in terms of and , that is, monotone and Lipschitz mappings (resp., monotone and bounded mappings).

Extension and Application of the Yamada Iteration Algorithm in Hilbert Spaces

Mathematics, 2019
In this paper, based on the Yamada iteration, we propose an iteration algorithm to find a common element of the set of fixed points of a nonexpansive mapping and the set of zeros of an inverse strongly-monotone mapping.

A New Iterative Algorithm for Zeros of Generalized Phi-strongly Monotone and Bounded Maps with Application

, 2016
Let E be a uniformly smooth and uniformly convex real Banach space and A : E → E ∗ be a generalized Φ-strongly monotone and bounded map with A − 1 (0) (cid:54) = ∅ .

On Invariant Hypersurfaces of Strongly Monotone Maps

Journal of Differential Equations, 1997
Let \(f:\mathbb{R}^m \to \mathbb{R}^m\) be a \(C^k\), \(k\geq 1\), diffeomorphism. Let \(f\) have positive derivative, that is the Jacobian matrix has positive entries for any \(x\in \mathbb{R}^m ...

Rheocasting versus Die Casting: An Insight into the Low‐Cycle Fatigue Behavior of AlSi7Mg0.6

Advanced Engineering Materials, EarlyView.
The study compares rheocast lightweight components with high‐pressure die cast materials regarding microstructure and fatigue behavior. Rheocast process offers higher efficiency due to lower casting temperatures. Despite some microstructural differences, both processes show similar strengths (yield strength 125 MPa, tensile strength 240 MPa).

An Extragradient Method and Proximal Point Algorithm for Inverse Strongly Monotone Operators and Maximal Monotone Operators in Banach Spaces

Fixed Point Theory and Applications, 2009
We introduce an iterative scheme for finding a common element of the solution set of a maximal monotone operator and the solution set of the variational inequality problem for an inverse strongly-monotone operator in a uniformly smooth and uniformly ...
