Explore how forces and friction work to hold a block against a vertical wall. This video explains normal force, frictional force, and equilibrium conditions, showing how these forces balance to ...

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 ...

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