We obtain the optimal system's generating operators associated with a generalized
Levinson–Smith equation; this one is related to the Liénard equation which is important for …

The position dependent nonconservative forces are called curl forces introduced recently by
MV Berry, P. Shukla, J. Phys. A 45, 305201 (2012). In this article, we elucidate the role of curl …

Noncentral force is an exemplary example of curl force and in general this is not an
integrable system. The purpose of this note is twofold. First, we study a different reduction in …

In this paper, we formulate a relativistic generalization of noncentral force, and it is a
prototypical example of relativistic curl force. We study reductions of relativistic noncentral …

We show the connection between the theory of Hamiltonian curl forces introduced by Berry
and Shukla and the cofactor systems introduced by the Linköping school. The linear curl …

A technique for the reconstruction of the potential for a scalar field in cosmological models
based on induced gravity has recently been developed by Alexander Y. Kamenshchik …

A bstract In this paper, a modified teleparallel gravity action containing a coupling be-tween
a scalar field potential and magnetism, in anisotropic and homogeneous backgrounds, is …

In this present communication, the relativistic formulation of the curl forces with saddle
potentials has been performed. In particular, we formulated the relativistic version of the …

The position-dependent non-conservative forces are called curl forces introduced recently
by Berry and Shukla (J Phys A 45: 305201, 2012). The aim of this paper is to study mainly …
