Rigidity results on gradient Schouten solitons

, 2020
In this paper we consider $\rho$-Einstein solitons of type $M= \left(B^n, g^{*}\right) \times (F^m,g_F)$, where $\left(B^n,g^{*}\right)$ is conformal to a pseudo-Euclidean space and invariant under the action of the pseudo-orthogonal group, and $\left(F ...

Optical solitons of NLS-type differential equations by extended direct algebraic method

International Journal of Geometric Methods in Modern Physics (IJGMMP), 2022
In this paper, we examine the optical soliton solutions of nonlinear partial differential equations belonging to the nonlinear Schrödinger (NLS) class which includes cubic focusing NLS equation and paraxial NLS equation in a Kerr media.

Pseudo-algebraic Ricci solitons on Einstein nilradicals

Advances in Geometry, 2021
We develop a variational method to find pseudo-algebraic Ricci solitons on connected Lie groups.As applications, we prove that every Einstein nilradical admits a non-Riemannian algebraic Ricci soliton, and that any algebraic Ricci soliton on a semi ...

Schouten-like Metrics on Five-Dimensional Nilpotent Lie Groups

International Electronic Journal of Geometry
The prescribed Ricci curvature problem consists of finding a Riemannian metric $g$ to satisfy the equation $Ric(g) = T$, for some fixed symmetric $(0,2)$-tensor field $T$ on a differential manifold $M$.

Optical solitons in birefringent fibers for Lakshmanan–Porsezian–Daniel model by modified extended direct algebraic method

Optik (Stuttgart), 2020
In this paper, the modified extended direct algebraic has been used to investigate the Lakshmanan–Porsezian–Daniel model. Many solutions such as bright, dark and combo optical soliton solutions are obtained.
