Resumen:
 An explicit 3-dimensional Riemannian metric is constructed which can  be interpreted as the (conformal) sum of two Kerr black holes with  aligned angular momenta. When the separation distance between them  is large we prove that this metric has positive Ricci scalar and  hence positive Yamabe invariant. This metric can be used to  construct axially symmetric initial data for two Kerr black holes  with large total angular momentum.
