Recently he has been awarded with the prestigious NSP fellowship of Slovak Government, to visit Slovak University of Technology, Bratsilava for two months later in this year. 

内容介绍：

    We introduce the notion of a middleman in a TU Cooperative game. The middleman engages in intermediary activities which increases the output of every coalition. For this, he offers a scheme of intermediary activities for each coalition and charges a fee in return. We propose a new solution called Intermediary value which is characterized using standard axioms in the literature. Some illustrative examples follow.
