摘要：

In this paper, we deal with weakly coupled elliptic systems A with unbounded coefficients. We prove the existence and characterize all the systems of invariant measures for the semigroup (T(t))(t >= 0) associated with A in C-b(R-d; R-m). We also show some relevant properties of the extension of (T(t))(t >= 0) to the L-P-spaces related to systems of invariant measures. Finally, we study the asymptotic behaviour of (T(t))(t >= 0) as t tends to +infinity.
