In the past several years, various methods have been proposed to obtain the exact optical soliton solutions of the non-linear Schrödinger equation [2 – 12]. Dispersion and non-linearity are two of the ...

A General Non-Linear Multilevel Structural Equation Mixture Model In this section, we will present a GNM-SEMM framework that allows for semiparametric latent non-linear effects on the within and the ...

This paper concerns with the problem of solving non-linear equation. It is shown that solving non-linear equation is equivalent to the evaluation extremum of funtion. In terms of unconstrained ...

In this paper the Painlevé test is performed for (2 + 1) dimensional non-linear Schrödinger equation Equation (1) as described in three steps constituting the Kruskal’s simplification algorithms such ...

We show that overall economic productivity is non-linear in temperature for all countries, with productivity peaking at an annual average temperature of 13 °C and declining strongly at higher ...
