We investigate the multisymplectic Euler box scheme for the Korteweg-de Vries (KdV) equation. A new completely explicit six-point scheme is derived. Numerical e
The wavefunctions that conserve the total spin are constructed for the fully condensed states and the states with one particle excited. A set of equations are d
The dispersion relations of the surface polariton in a semi-infinite wire medium with spatial dispersion are analysed.In comparison with the traditional spatial
The global asymptotic stability of delayed Cohen-Grossberg neural networks with impulses is investigated. Based on the new suitable Lyapunov functions and the J
