In this paper, we investigate the traveling wave solutions for the nonlinear dispersive equation, Korteweg-de Vries Zakharov鈥揔uznetsov(Kd V-ZK) equation and complex coupled Kd V system by using extended simplest equation method, and then derive the hyperbolic function solutions include soliton ...
摘要: By virtue of the "invariant eigen-operator" method which originates from the Heisenberg equation of motion, we derive energy-level gap of some dynamic Hamiltonians in many particle physics, which includes a Tomonaga model and spin wave model.关键词:...

As is known, the voltage between two spaced points a and b is defined by the equation: ##EQU1## where E(x) is the field gradient at x and the integral is independent of path. Thus, in order to accurately measure the voltage between spaced points a and b, it is necessary that a ...
This paper presents a new way for deriving solitary wave by using variational principle, which not only can be used to derive solitary wave according to Original Mathematical Equations (OME), but also can be used to derive solitary wave according to the Wave Equation (WE) derived from OME. ...
wave in any medium. This unified equation includes the effects of motion, if present, of the medium relative to the observer as well as the relative velocity between the observer and the source. This master equation can be applied to both relativistic and nonrelativistic situations to recover ...
Since the expansion of this six-order determinant was not shown in both two papers, it has been difficult to readers to recognize these misprints. This paper presents a technique that provides a totally explicit secular equation of the wave. The technique makes clear the way from the traction-...
