Hamiltonian evolutionary games

Abstract: Abstract. We introduce a class of o.d.e.'s that generalizes to polymatrix games the replicator equations on symmetric and asymmetric games. We also introduce a new class of Poisson structures on the phase space of these systems, and characterize the corresponding subclass of Hamiltonian polymatrix replicator systems. This extends known results for symmetric and asymmetric replicator systems.

“…The constant of motion forX B is the primitive of the 1-form (1 + n−1 i=1 e ui ) D t η q . This result relaxes the skew-symmetric condition on B which is required at [2].…”

“…Our results: In this paper we consider replicator equations and study their constants of motion and Hamiltonian character using Dirac and big-isotropic structures. Our work here is a continuation of what is done in [2] where for a more general class of equations, i.e. polymatrix replicator equations, a class of poisson structures on their phase space was introduced and the corresponding subclass of Hamiltonian polymatrix replicators were characterised.…”
