Explicit Lump and New Closed-Form Analytical Outcomes for the Nonlinear Hyperbolic Schrödinger Equation
摘要
The hyperbolic Schrödinger equation (SE) is a variant of nonlinear SE and is used in the study of ultrashort optical pulse prorogation in nonlinear media when the paraxial envelop approximation is not valid. In this work, we investigate a nonlinear hyperbolic Schrödinger equation (SE) via two distinct analytical approaches: the first one is the Hirota method (HM), and the other is the
