Petri nets are a formal model of concurrent systems. They were first defined by Petri in
his thesis [Pet62] and were presented at the IFIP 1962 congress in Munich [Pet63]. Nets
are widely used in modelling various aspects ...

This work is about analysing reasoning about games - specially the social network
games, polymatrix games, priority separable games and large games. Towards the
reasoning we employ di↵erent logics - namely the least fixed ...
