Backstepping controller design for a class of stochastic nonlinear systems with Markovian switching [PDF]

open access: yes, 2008
A more general class of stochastic nonlinear systems with irreducible homogenous Markovian switching are considered in this paper. As preliminaries, the stability criteria and the existence theorem of strong solutions are first presented by using the ...

Fixed Point Results in Neutrosophic b- Metric Like Spaces [PDF]

open access: yesNeutrosophic Sets and Systems
In this manuscript we introduce the idea of Neutrosophic b-metric like spaces along with numerous significant illustrations. Moreover, we present numerous fixed point results in Neutrosophic b-metric like space and we gave some examples to support our ...

Existence of bounded solutions for retarded equations with infinite delay, impulses, and nonlocal condition

open access: yesNOVASINERGIA, 2020
In this work, we study the existence of bounded solutions for a semilinear retarded equation with infinite delay, impulse, and non-local conditions. We also show that under some conditions this bounded solution is unique, periodic, or almost periodic ...

Equations, Contractions, and Unique Solutions [PDF]

open access: yesProceedings of the 42nd Annual ACM SIGPLAN-SIGACT Symposium on Principles of Programming Languages, 2015
One of the most studied behavioural equivalences is bisimilarity. Its success is much due to the associated bisimulation proof method, which can be further enhanced by means of “bisimulation up-to” techniques such as “up-to context.”A different proof method is discussed, based on a unique solution of special forms of inequations called contractions and

Gluing Non-unique Navier–Stokes Solutions

open access: yesAnnals of PDE, 2023
AbstractWe construct non-unique Leray solutions of the forced Navier-Stokes equations in bounded domains via gluing methods. This demonstrates a certain locality and robustness of the non-uniqueness discovered by the authors in [1].

Equilibrium solution to the lowest unique positive integer game

open access: yes, 2010
We address the equilibrium concept of a reverse auction game so that no one can enhance the individual payoff by a unilateral change when all the others follow a certain strategy.

A Universal Ordinary Differential Equation

open access: yes, 2020
An astonishing fact was established by Lee A. Rubel (1981): there exists a fixed non-trivial fourth-order polynomial differential algebraic equation (DAE) such that for any positive continuous function $\varphi$ on the reals, and for any positive ...

On a unique solution of fractional differential system

open access: yesTikrit Journal of Pure Science, 2019
The aim of the study is to investigate the existence and uniqueness of solutions for a semi linear fractional differential system via Banach fixed point theorem.

Unique continuation property with partial information for two-dimensional anisotropic elasticity systems

open access: yes, 2020
In this paper, we establish a novel unique continuation property for two-dimensional anisotropic elasticity systems with partial information. More precisely, given a homogeneous elasticity system in a domain, we investigate the unique continuation by ...

Unique-Solution Single-Sample Complex Dielectric Characterization Through Linear Phase Approximation

open access: yesIEEE Open Journal of Antennas and Propagation, 2022
This paper presents a transmission-only (TO) approach that solves the long-standing problem of transmission phase ambiguity. The approach considers a linear frequency-dependent phase approximation to derive the phase mode value analytically and uniquely ...
