Title in Portuguese
Estimativas a priori para jogos de campo médio com dinâmica populacional logística
Keywords in Portuguese
Equações Diferenciais Parciais
Abstract in Portuguese
Jogos de campo médio são sistemas acoplados de equações diferenciais parciais, uma equação de Hamilton-Jacobi para a função valor dos agentes e uma equação de Fokker-Planck para a densidade dos agentes. Tradicionalmente, a última equação é adjunta à linearização da primeira. Uma vez que a equação de Fokker-Planck modela uma dinâmica populacional, nós introduzimos características naturais como semeadura e nascimento e também taxas de mortalidade não-lineares. Neste trabalho analizamos um jogo de campo médio estacionário, ilustrando várias técnicas para obter a regularidade a priori das soluções nesta classe de sistemas. Sistemas estes que apresentam dinâmica logística com semeadura. O sistema de dimensão um é estudado separadamente num contexto simplicado.
Title in English
A priori estimates for mean eld games with logistic populational dynamics
Abstract in English
A mean eld game is a coupled system of partial dierential equations, a Hamilton-Jacobi equation for the value function of agents and a Fokker-Planck equation for the density of agents. Traditionally, the latter equation is adjoint to the linearization of the former. Since the Fokker-Plank equation models a populational dynamic, we introduce natural features such as seeding and birth, and non-linear death rates. In this thesis we analyze a stationary mean eld game, illustrating various techniques to obtain a priori regularity of solutions in this class of systems. This system shows logistic dynamics with seeding. The one dimensional system is studied separately in a simplied context.
