Neste trabalho, apresentamos uma introdução à Teoria de semigrupos analíticos de operadores lineares não limitados, sendo desenvolvidas algumas aplicações desta Teoria na análise da existência de solução para as equações Diferenciais Ordinárias em espaços de Banach da forma u1(t)−Au(t)= f(t,u(t))+K(u)(t), onde f e K são funções dadas e A é um operador linear não limitado.In this work we present an introduction to the Theory of analytical semigroups of unbounded linear operators, with some applications of this theory to the existence of solutions for Ordinary Differential equations in Banach spaces of form: u1(t)−Au(t)= f(t,u(t))+K(u)(t), where f e K are given functions and A is an unbounded operator.CNPqCape
