A General Inertial Projection-Type Algorithm for Solving Equilibrium Problem in Hilbert Spaces with Applications in Fixed-Point Problems

Axioms, 2020
A plethora of applications from mathematical programming, such as minimax, and mathematical programming, penalization, fixed point to mention a few can be framed as equilibrium problems.

Alterations of Functional Brain Connectivity After Long-Duration Spaceflight as Revealed by fMRI

Frontiers in Physiology, 2019
The present study reports alterations of task-based functional brain connectivity in a group of 11 cosmonauts after a long-duration spaceflight, compared to a healthy control group not involved in the space program.

Spaceflight-induced neuroplasticity in humans as measured by MRI: what do we know so far?

npj Microgravity, 2017
Space travel poses an enormous challenge on the human body; microgravity, ionizing radiation, absence of circadian rhythm, confinement and isolation are just some of the features associated with it.

Common Solution for a Finite Family of Equilibrium Problems, Inclusion Problems and Fixed Points of a Finite Family of Nonexpansive Mappings in Hadamard Manifolds [PDF]

Sahand Communications in Mathematical Analysis
In this paper, we present an iterative algorithm and prove that the sequence generated by this algorithm converges strongly to a common solution of a finite family of equilibrium problems, the quasi-variational inclusion problem and  the set of common ...

Optimizing transcranial magnetic stimulation for spaceflight applications

npj Microgravity, 2023
As space agencies aim to reach and build installations on Mars, the crews will face longer exposure to extreme environments that may compromise their health and performance.

A new extragradient algorithm with adaptive step-size for solving split equilibrium problems

Journal of Inequalities and Applications, 2021
He (J. Inequal. Appl. 2012:Article ID 162 2012) introduced the proximal point CQ algorithm (PPCQ) for solving the split equilibrium problem (SEP). However, the PPCQ converges weakly to a solution of the SEP and is restricted to monotone bifunctions.

Reducibility among equilibrium problems

Proceedings of the thirty-eighth annual ACM symposium on Theory of Computing, 2006
We address the fundamental question of whether the Nash equilibria of a game can be computed in polynomial time. We describe certain efficient reductions between this problem for normal form games with a fixed number of players and graphical games with fixed degree.

Approximations of Equilibrium Problems

SIAM Journal on Control and Optimization, 2012
In this paper we study the scalar equilibrium problem (EP). We employ variational convergences of bifunctions (lopsided convergence in the maxinf framework, hypo-convergence, and continuous convergence) to study this problem by means of an approximation method. This method allows us to obtain not only existence but also stability results.

A viscosity iterative technique for equilibrium and fixed point problems in a Hadamard space

Applied General Topology, 2019
The main purpose of this paper is to introduce a viscosity-type proximal point algorithm, comprising of a nonexpansive mapping and a finite sum of resolvent operators associated with monotone bifunctions. A strong convergence of the proposed algorithm to

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.
