A Discrete Variational Approach for Investigation of Stationary Localized States In A Discrete Nonlinear Schr$\ddot{\mathbf{o}}$dinger Equation, Named IN-DNLS

K. Kundu

IN-DNLS, considered here is a countable infinite set of coupled one dimensional nonlinear ordinary differential difference equations with a tunable nonlinearity parameter, $\nu$. Thi…
