Anisotropic equations: Uniqueness and existence results

open access: yesDifferential and Integral Equations, 2008
We study uniqueness of weak solutions for elliptic equations of the following type \[ -\partial_{x_{i}}\left( a_{i}(x,u)\left\vert \partial_{x_{i}}u\right\vert ^{p_{i}-2}\partial_{x_{i}}u\right) +b(x,u) =f(x), \] in a bounded domain $\Omega\subset{\mathbb{R}}^{n}$ with Lipschitz continuous boundary $\Gamma=\partial\Omega$.

Optimal pair of fixed points: existence, uniqueness and approximation

open access: yesFixed Point Theory and Algorithms for Sciences and Engineering
In this paper, we introduce a novel class of mappings, referred to as noncyclic generalized θ-contractions. By employing the geometric concept of W U C $WUC$ property in metric spaces, we establish new existence and convergence theorems for the fixed ...

Existence of solutions to fractional order ordinary and delay differential equations and applications

open access: yesElectronic Journal of Differential Equations, 2011
In this article, we discuss the existence and uniqueness of solution to fractional order ordinary and delay differential equations. We apply our results on the single species model of Lotka Volterra type.

Existence and uniqueness for a Ginzburg-Landau system for superconductivity

open access: yesElectronic Journal of Differential Equations, 2020
We prove the existence of a unique solution for a time-dependent Ginzburg-Landau model in superconductivity under the Coulomb gauge. Also we prove the uniform-in-$\epsilon$ well-posedness of the solution, where $\epsilon$ is the coefficient of the ...

Liapunov fundtions and global existence without uniqueness [PDF]

open access: yesProceedings of the American Mathematical Society, 1970
In a recent paper J. Kato and A. Strauss character- ized the global existence of solutions of ani ordinary differenitial equation in terms of Liapunov functions in which they assumed the right hand side of the differential equatioln is locally Lipschitz. In the present paper a characterization of global existence of an ordinary differential equation is

Existence and Uniqueness of Second-Order Impulsive Delay Differential Systems

open access: yesAxioms
In this paper, we study the existence and uniqueness of second-order impulsive delay differential systems. Firstly, we define cosine-type and sine-type delay matrix functions, which are used to derive the solutions of the impulsive delay differential ...
