It is widely acknowledged in the socio-economic literature that innovators and early adopters play an essential role in the diffusion of innovation. However, current approaches to influence maximization primarily concentrate on identifying influencers as the main targets of marketing campaigns....

We consider linearly weighted versions of the least core and the (pre)nuceolus and investigate the reduction possibilities in their computation. We slightly extend some well-known related results and establish their counterparts by using the dual game. Our main results imply, for example, that...

We characterize the assignment games which admit a population monotonic allocation scheme (PMAS) in terms of efficiently verifiable structural properties of the nonnegative matrix that induces the game. We prove that an assignment game is PMAS-admissible if and only if the positive elements of...
