Derivative Nonlinear Schrödinger Equations (DNLS) extend the classical nonlinear Schrödinger framework by incorporating derivative-dependent nonlinearities. This modification enriches the model's ...

Microsoft Excel doesn't have the ability to generate a derivative equation from a given formula, but you can still use the program to calculate values for both a formula and its derivative and plot ...

The derivative nonlinear Schröndinger equation (DNLS) $iq_t = q_{xx} \pm (q^\ast q^2)_x, & q = q(x, t), i = \sqrt{-1}, q^\ast(z) = \overline{q(z)}$, was first ...

In this paper we consider the local well-posedness theory for the quadratic nonlinear Schrödinger equation with low regularity initial data in the case when the nonlinearity contains derivatives. We ...
