                         din{\^a}micos em s{\'e}ries temporais e, talvez o mais 
                         importante, a an{\'a}lise de s{\'e}ries temporais pode fornecer 
                         um conjunto de ferramentas {\'u}teis para a 
                         caracteriza{\c{c}}{\~a}o de redes complexas de uma forma 
                         totalmente original. ABSTRACT: Recently, several mappings from a 
                         time series to a network have been proposed with the intent of 
                         using network metrics to characterize time series. Although these 
                         mappings demonstrate that different time series result in networks 
                         with distinct topological properties, it remains unclear how these 
                         topological properties relate to the original time series. Here, 
                         it was proposed an intuitive mapping from a time series to a 
                         network with an approximate inverse operation, making it possible 
                         to use network statistics to characterize time series and time 
                         series statistics to characterize networks. As a proof of concept, 
                         an ensemble of time series ranging from periodic to random were 
                         generated and confirm that the proposed mapping retains much of 
                         the information encoded in the original time series and networks 
                         after repeated application of the mapping and its inverse. The 
                         results obtained in this thesis suggest that network analysis can 
                         be used to distinguish different dynamic regimes in time series 
                         and, perhaps more importantly, time series analysis can provide a 
                         powerful set of tools that augment the traditional network 
                         analysis toolkit to quantify networks in new and useful ways.",
