| Abstract: | Two-phase quasi-periodic solutions of the sine-Gordon equation are discussed. It is shown that the solutions expressed by the multidimensional θ-function form a broader class than the well-known factorised solutions 4 arctan f(u)g(v)]. Expressions describing the spatial and temporal period are also given. |
