In this paper, using topological degree and linear algebra techniques, we prove that a certain class of quasi-linear systems of differential equations of the form αΊ = Ax + ΞΌf (x, ΞΌ) has at least one periodic solution, where ΞΌ is a small parameter and A is a constant n Γ n matrix. If ΞΌ is bounded awa
