Candogan et al. (2011) provide an orthogonal direct-sum decomposition of finite games into potential, harmonic and non-strategic components.
In this paper we study the issue of decomposing games that are strategically
equivalent from a game-theoretical point of view, for instance games obtained
via duplications of strategies or suitable linear transformations of payoffs. We
consider classes of decompositions and show when two decompositions of equivalent games are coherent.
