To do this, we use the method of sub and supersolution in combination with variational methods and the maximum principle. / Nesta dissertação, provamos a existência e multiplicidade de soluções fracas positivas para algumas classes de problemas elípticos no plano envolvendo crescimento exponencial do tipo Trudinger-Moser com condição de Neumann na fronteira. Para isso, usaremos o método de sub e supersolução em combinação com métodos variacionais e o princípio do máximo.
