Riccati equations for bounded radiating systems
S. D. Maharaj, A. K. Tiwari, R. Mohanlal +1
We systematically analyze the nonlinear partial differential equation that determines the behaviour of a bounded radiating spherical mass in general relativity. Four categories of…
Radiating stars with exponential Lie symmetries
R. Mohanlal, S. D. Maharaj, A. K. Tiwari +1
We analyze the general model of a radiating star in general relativity. A group analysis of the under determined, nonlinear partial differential equation governing the model's grav…
The inverse problem of a mixed Liénard type nonlinear oscillator equation from symmetry perspective
Ajey K. Tiwari, S. N. Pandey, V. K. Chandrasekar +2
In this paper, we discuss the inverse problem for a mixed Liénard type nonlinear oscillator equation , where and are…
Factorization technique and isochronous condition for coupled quadratic and mixed Liénard-type nonlinear systems
Ajey K. Tiwari, V. K. Chandrasekar, S. N. Pandey +1
In this paper, we discuss a systematic and self consistent procedure to factorize a rather general class of coupled nonlinear ordinary differential equations (ODEs), namely coupled…
On the complete Lie point symmetries classification of the mixed quadratic-linear Linard type equation
Ajey K. Tiwari, S. N. Pandey, M. Senthilvelan +1
In this paper we develop a systematic and self consistent procedure based on a set of compatibility conditions for identifying all maximal (eight parameter) and non-maximal (one an…
Classification of Lie point symmetries for quadratic Linard type equation
Ajey K. Tiwari, S. N. Pandey, M. Senthilvelan +1
In this paper we carry out a complete classification of the Lie point symmetry groups associated with the quadratic Linard type equation, $\ddot {x} + f(x){\dot {x}}^{2}…
