Equilibrium problems and variational inequalities form a crucial mathematical framework for modelling systems where multiple agents or factors interact under specific constraints. An equilibrium ...

Ekeland’s variational principle serves as a fundamental tool in modern optimisation theory, offering a framework to identify approximate solutions under minimal assumptions. Its versatility has ...

For the past six years, Los Alamos National Laboratory has led the world in trying to understand one of the most frustrating barriers that faces variational quantum computing: the barren plateau.
