Applying the Fourier pseudospectral method to space derivatives and the symplectic Euler rule to time derivatives in the multisymplectic form of the Klein–Gordon–Zakharov equations,we derive an explicit multisymplec...

The one-and two-particle states in the sinh-Gordon and sine-Gordon models in(1+1)dimensions are investigated by using the gaussian wave-functional approach.We find that(i)the renormalized mass parameter is just the va...
