Graphs are useful for studying how components of networks that arise in commerce, the social sciences, medicine, and other areas interrelate. For example, graphs are useful for studying the spread of a contagious disease or a network of commercial flights serving a number of large cities. Graph theory is a very broad topic. In this work, only a few definitions will be presented and the close relationship between graph theory and matrix theory will be shown.Acesso AbertoPesquisa matemáticaTeoria dos grafosTeoria das matrizesMathematical ResearchGraph TheoryMatrix TheoryTrabalho de Conclusão de CursoCIENCIAS EXATAS E DA TERRA
