The first specific objective is to determine the general solution of the Langevin equation [2] and use it for our model. The second specific objective is the construction of new treelike small-world networks, using programming techniques (Fortran). Another objective is the numerical determination of the eigenvalues of the connectivity matrix for small-world networks, which will solve the dynamics. Knowing the eigenvalues’ spectrum we calculate the average polymer displacement and the complex modulus. / O objetivo geral deste trabalho é o estudo teórico da dinâmica de polímeros flexíveis com topologia de mundo pequeno através do modelo de Rouse[1]. O primeiro objetivo específico é determinar a solução geral da equação de Langevin[2] e aplicá-la para nosso modelo. O segundo objetivo específico é a construção de novas redes de mundo pequeno de tipo árvore, usando as técnicas de programação (Fortran). Outro objetivo é a determinação numérica dos autovalores da matriz de conectividade para as redes de mundo pequeno, que resolverá a dinâmica. Conhecendo o espectro dos autovalores calcularemos o deslocamento médio dos polímeros e o módulo complexo.
