| Abstract: | We present symplectic and multisymplectic formulations of the Klein-Gordon equation in this paper. Based on these two formulations,
we investigate the corresponding symplectic and multisymplectic Fourier pseudospectral discretizations. The relationship between
these two kinds of Fourier pseudospectral discretizations is discussed. Time discretizations are also presented. |
