Quanto ao conjunto dos números complexos, um importante resultado é que todo polinômio de grau n (maior ou igual a 1) e com coeficientes complexos tem n raízes complexas. De modo geral, o presente trabalho tem o objetivo de contextualizar algumas aplicações das raízes da unidade na matemática. Apresentamos sua aplicação em um caso particular do Teorema de Dirichlet, na construção de reticulados, cuja utilidade está ligada a problemas de transmissão de sinal, e na história da resolução do Último Teorema de Fermat. / The search for the solution of some relevant problems, or even of equations, has been a source of inspiration to extend the numerical sets. As for the set of complex numbers, an important result is that every polynomial of degree n (bigger or equal 1) and with complex coefficients has n complex roots. In general, the present work aims to contextualize some applications of the roots of unit in mathematics. We present its application in a particular case of the Dirichlet Theorem, in the construction of lattices, whose utility is linked to signal transmission problems, and in the history of the resolution of the Fermat's Last Theorem.
