Abstract

The two breathers solution to the nonlinear coupled Klein-Gordon equation is analyzed to show that the breather resonances exist between them. There are two types of singular interactions: One is the resonant interaction where two breathers interact so as to make a new breather, the other is the extremely long-range interaction where two breathers interact infinitely apart from each other.
