proportional excess. Based on this so-called alpha-excess, we define new solution concepts for cooperative games, such as the alpha …-prenucleolus and the alpha-prekernel. The classical prenucleolus and prekernel are a special case. We characterize the alpha …-prekernel by strong stability and the alpha-balanced surplus property. Also, we show that the payoff vector generated by the alpha …
