Quelques thèmes en l'analyse variationnelle et optimisation / Some topics in variational analysis and optimizationNguyen, Le Hoang Anh 23 February 2014 (has links)
Dans cette thèse, j’étudie d’abord la théorie des [gamma]-limites. En dehors de quelques propriétés fondamentales des [gamma]-limites, les expressions de [gamma]-limites séquentielles généralisant des résultats de Greco sont présentées. En outre, ces limites nous donnent aussi une idée d’une classification unifiée de la tangence et la différentiation généralisée. Ensuite, je développe une approche des théories de la différentiation généralisée. Cela permet de traiter plusieurs dérivées généralisées des multi-applications définies directement dans l’espace primal, tels que des ensembles variationnels,des ensembles radiaux, des dérivées radiales, des dérivées de Studniarski. Finalement, j’étudie les règles de calcul de ces dérivées et les applications liées aux conditions d’optimalité et à l’analyse de sensibilité. / In this thesis, we first study the theory of [gamma]-limits. Besides some basic properties of [gamma]-limits,expressions of sequential [gamma]-limits generalizing classical results of Greco are presented. These limits also give us a clue to a unified classification of derivatives and tangent cones. Next, we develop an approach to generalized differentiation theory. This allows us to deal with several generalized derivatives of set-valued maps defined directly in primal spaces, such as variational sets, radial sets, radial derivatives, Studniarski derivatives. Finally, we study calculus rules of these derivatives and applications related to optimality conditions and sensitivity analysis.

Hybrid macro-particle moment accelerator tracking algorithmJung, Paul Matthew 27 August 2020 (has links)
A particle accelerator simulation which straddles the gap between multi-particle and moment codes is derived. The hybrid approach represents the
beam using macro-particles which contain discrete longitudinal coordinates
and transverse second moments. The discretization scheme for the macro-particles is derived using variational principles, as a natural extension of well
known variational approaches. This variational discretization allows for exact
transverse emittance conservation. The electrostatic self-potential is discrete
in the longitudinal direction and solved semi-analytically in the transverse
direction using integrated Green’s functions. The algorithm is implemented
and tested against both a moment and multi-particle code. / Graduate
