SUMMARY:

In this work we propose a method capable of quantifying the synchronization between
two distinct parameters of a time-varying system, which can be described
using multilayer networks. In this method, we consider connections as a factor
essential in obtaining the synchronization measure. This being evaluated from two
perspectives: the co-occurrence of connections of different parameters in relation to time and,
regarding the attendance of connections.
The construction of this method is based on the concept of networks, as in the first
chapter of this thesis we approach a brief introduction about graph theory and its
basic indices of analysis of a system. The systems considered here exhibit changes
over time, and are evaluated based on different parameters. In view of this,
the concepts of time-varying graphs - GVT [1] and multilayer networks [2–4] also
are discussed in this chapter.
We also present in Chapter 1 a description of the synchronization method by
motifs [5] developed by Rosário and collaborators, which transforms time series into
time-varying networks, as this method will be used in our work. Is for
At the end of the chapter, we present the Incidence and Loyalty indices [6] developed in the
the study of word networks and which served as a basis for the design of our proposal.
Chapter 2 follows the article format and, therefore, the first part is
composed of: abstract, keywords and introduction. In sections 2.2 and 2.3, we present
our methodology and the validations developed. Its application is discussed in the section
next, where we consider the synchronization of different combinations of 4 variables
climatic conditions of the 417 cities of the state of Bahia in a period of 17 years. in the last section
of the chapter, section 2.5, we present the final conclusions about the developed method and
about your application.
Finally, we have two appendices. In the first one, we justify the choice of the values of the
parameters of the motif synchronization method [5]. And, in the second, we discuss
simplified form on the biomes found in the state of Bahia.
