Dentre tais propriedades estudamos a existência de tais soluções assim como questões de periodicidade, para o problema de Cauchy abstrato com retardo dependendo do estado e para o problema com semigrupo exponencialmente estável. E para a equação que modela a dinâmica das estruturas flexíveis, esturademos a propriedade de Kneser. / In the present study, we focused on properties related to mild solutions to certain types of evolution equations. Among such properties, we studied the existence of these solutions as well as periodicity problems to the abstract Cauchy problem with state dependent delay and to the hyperbolic semigroup problem. In addition, for the equation that models the dynamic of flexible structures we studied the Kneser property.
