Sažetak

A simple cosmology with slowly growing Newton's coupling constant motivated from Brans-Dicke coupling theory and decaying vacuum energy density in universe with flat spatial curvature is considered. Despite the simplicity of the model, it exhibits interesting late-time dynamics consequences in agreement with recent observations.
