Abstract: In nonlinear programming, the notion of quasinormality provides a constraint qualification which is in general weaker than that of normality, and it emerges naturally from an extended Lagrange multiplier rule. In this paper, we explain in detail its origin and some of its consequences in optimization theory for finite dimensional problems involving equality and inequality constraints, and provide a possible generalization to optimal control problems.
