Resum:	A one-parameter family of differential systems that bridges the gap between the Lorenz and the Chen systems was proposed by Lu, Chen, Cheng and Celikovsy. The goal of this paper is to analyze what we can say using analytic tools about the dynamics of this one-parameter family of differential systems. We shall describe its global dynamics at infinity, and for two special values of the parameter a we also can describe the global dynamics in the whole R 3 using the invariant algebraic surfaces of the family. Additionally we characterize the Hopf bifurcations of this family.
