There are two recognized classes of strategic-form symmetric games, both of which can be conveniently defined through the corresponding player symmetry groups. We investigate the basic properties of these groups and several related concepts. We generalize the notion of coveringness of...

The Colonel Blotto Game is one of the most classical zero-sum games, with diverse applications in wars, auctions, political elections and anti-terrorists etc. We consider the discrete two-battlefield Colonel Blotto Game, a basic case that has not been completely characterized yet. We study three...

Games with strategic substitutes (GSS) are generally less tractable than games with strategic complements (GSC). This paper revisits the GSC versus GSS comparison by establishing a novel connection between them. We show through a network perspective that, when the strategy set of each player is...
