Seminários de Sistemas Estocásticos e Dinâmicos
Instituto de Matemática, Estatística e Computação Científica - Unicamp
|
Seminários do grupo de Sistemas Estocásticos e Dinâmicos, integrado por pesquisadores voltados ao estudo de propriedades interligadas de Dinâmica, Geometria e Análise Estocástica. Os membros deste grupo usam técnicas em comum de Probabilidade, Dinâmica e Teoria Ergódica. As áreas estão concentradas em: dinâmica estocástica em variedades, EDPs estocásticas, difusões em espaços folheados, decomposição de fluxos estocásticos e suas aplicações, sistemas acoplados e equilíbrio para autômatos celulares com memória. Se tiver interesse em receber mais informações, entre em contato.
