Abstract
In this work, we introduce Rock-Paper-Scissors lattice model on Cayley tree of second order
generated by Rock-Paper-Scissors game. In this strategic 2-player game, the rule is simple: rock
beats scissors, scissors beat paper, and paper beats rock. A payoff matrix A of this game is a skewsymmetric.
It is known that quadratic stochastic operator generated by this matrix is non-ergodic transformation. The Hamiltonian of Rock-Paper-Scissors Lattice Model is defined by this skewsymmetric payoff matrix A . In this paper, we discuss a connection between three fields of research:
evolutionary games, quadratic stochastic operators, and lattice models of statistical physics. We prove
that a phase diagram of the Rock-Paper-Scissors model consists of translation-invariant and periodic
Gibbs measure with period 3.
