Dispersion relation of the nonlinear Klein-Gordon equation through a variational method

Here, the λϕ 4 and the sine-Gordon scalar theories are used to illustrate how nonperturbative effects far beyond the Gaussian approximation are obtained by considering the

Generalized (G’/G)-expansion method and exact traveling wave solutions of the perturbed nonlinear Schr¨odinger’s equation with Kerr law nonlinearity in optical fiber

Government policy varies between nations and this guidance sets out the need for balanced decision-making about ways of working, and the ongoing safety considerations

On the other hand at Alalakh Level VII and at Mari, which are the sites in the Semitic world with the closest affinities to Minoan Crete, the language used was Old Babylonian,

The main goal of this work is to extend the Hamilton-Jacobi theory to different geometric frameworks (reduction, Poisson, almost-Poisson, presymplectic...) and obtain new ways,

We have observed that the cosmsinmT method has a lower relative error for 877 and 1257 of the 2500 matrices than the cosmsinmP method for computing the approximate values of the

Dispersion of the time domain wavelet Galerkin method based on Daubechies’ compactly supported scaling functions with three and four vanishing moments. Fujii

In this section we will construct the quantum group for several physically interesting systems as an application of the formalism presented above: the conformally-invariant
