This paper focus on new optical soliton solutions of a nonlinear Schrodinger equation with self-frequency shift , and kerr nonlinearity terms. We utilize the extended version of modified tanh expansion technique associated with new Riccati solutions. We extract optical soliton solutions such as dark and bright optical solitons, breathers type, periodic

Riccati technique and oscillation constant for modified Euler type half-linear equations
Publicationes Mathematicae Debrecen, 2020Studovany jsou pololinearni diferencialni rovnice se skalarnim libovolně daným p-laplasianem. Je znamo, že tyto rovnice jsou podminěně oscilatoricke pro jiste koeficienty. Podminěna oscilace pro jiste nekonstatni koeficienty byla dokazana pomoci Pruferova uhlu. Pomoci nove modifikace Riccatiho metody (tj. pomoci rozdilneho přistupu) jsou identifikovany
