Robust Ekeland variational principles. Application to the formation and stability of partnerships

This paper has two parts. The mathematical part provides generalized versions of the robust Ekeland variational principle in terms set-valued EVP with variable preferences, uncertain parameters and changing weights given to vectorial perturbation functions. behavioural that motivates our findings models formation stability a partnership changing, complex environment context rationality approach stop, continue go human dynamics. Our generalizations allow us consider very important psychological effects relative ego depletion goal gradient hypothesis.
