Convergence, interpolation, échantillonnage et bases de Riesz dans les espaces de Fock / Convergence, interpolation, sampling and Riesz bases in the Fock spaces

Dumont, Andre 08 November 2013 (has links)
Nous étudions le problème d'unicité, de l'interpolation faible et de la convergence de la série d'interpolation de Lagrange dans les espaces de Fock pondérés par des poids radiaux. Nous étudions aussi les suites d'échatillonnage, d'interpolation et les bases de Riesz dans les petit espaces de Fock. / We study the uniqueness sets, the weak interpolation sets, and convergence of the Lagrange interpolation series in radial weighted Fock spaces. We study also sampling, interpolation and Riesz bases in small radial weighted Fock spaces

No. of bitstreams: 2 license_rdf: 1232 bytes, checksum: 66e71c371cc565284e70f40736c94386 (MD5) Fock space approach to Schnakenberg model.pdf: 6802590 bytes, checksum: 388dea2a463bd63474eaab61feece049 (MD5) Previous issue date: 2016-05-24 / Capes / This work has as objective to study the relationship between Fock spaces, quantum operators and chemical reaction systems used to model many stochastic processes with biological motivation, such as population growth, heartbeats and cell metabolism. In particular, we work with a generalization of Schnakenberg model, in its deterministic and stochastic versions, and which is used to describe the process of cellular glycolysis. As it is a new and at the same time a interdisciplinary area, involving knowledge in stochastic processes, theoretical physics, chemistry and biomathematics, this text seeks to be self-contained, including all the elements needed for the study of theme, for the purpose of contribute to the better understanding between these diverse areas. / Este trabalho tem como objetivo estudar a relação entre espaços de Fock, operadores de mecânica quântica e sistemas de reações químicas usados para modelar diversos processos estocásticos com motivação biológica, como crescimento populacional, batimentos cardíacos e metabolismo celular. Em particular, vamos trabalhar com uma generalização do modelo de Schnakenberg, em suas versões determinística e estocástica, e que pode ser utilizado para descrever o processo de glicólise celular. Como é uma área recente e ao mesmo tempo interdisciplinar, envolvendo conhecimento em processos estocásticos, física teórica, química e biomatemática, este texto procura ser autocontido, incluindo todos os fundamentos necessários para o estudo do tema, visando contribuir para o melhor entendimento entre estas diversas áreas.
