Bounded perturbation resilience of extragradient-type methods and their applications. [PDF]
In this paper we study the bounded perturbation resilience of the extragradient and the subgradient extragradient methods for solving variational inequality (VI) problem in real Hilbert spaces. This is an important property of algorithms which guarantees

Asymptotically linear magnetic fractional problems [PDF]
The aim of this paper is investigating the existence and multiplicity of weak solutions to non--local equations involving the {\em magnetic fractional Laplacian}, when the nonlinearity is subcritical and asymptotically linear at infinity. We prove existence and multiplicity results by using variational tools, extending to the magnetic local and non ...

đť‘šth roots of the identity operator and the geometry conjecture [PDF]
In this paper, we give three different new proofs of the validity of the geometry conjecture about cycles of projections onto nonempty closed, convex subsets of a Hilbert space.

Multiplicity and concentration of semi-classical solutions to nonlinear Dirac-Klein-Gordon systems
In the present article, we study multiplicity of semi-classical solutions of a Yukawa-coupled massive Dirac-Klein-Gordon system with the general nonlinear self-coupling, which is either subcritical or critical growth.

Multiplicity and minimality of periodic solutions to fourth-order super-quadratic difference systems
In this article, we use the Nehari manifold method to study a class of fourth-order even difference systems. First, we show that there exist multiple periodic solutions to the non-autonomous system.

The concentration-compactness principles for Ws,p(·,·)(ℝN) and application
We obtain a critical imbedding and then, concentration-compactness principles for fractional Sobolev spaces with variable exponents. As an application of these results, we obtain the existence of many solutions for a class of critical nonlocal problems ...
