Conservation Laws of Einstein�s Field Equations for Pure Radiation Fields
(Springer Science and Business Media Deutschland GmbH, 2020-09-30)
In the present paper, conservation laws of some of Einstein�s field equations are�obtained. Two methods are used to obtain conservation�laws. Firstly, direct method via multiplier approach is used and then, new conservation ...
Explicit Exact Solutions and�Conservation Laws of�Modified ? Equation
(Springer Science and Business Media Deutschland GmbH, 2022-10-13)
The invariant solutions of generalised modified ? equation are obtained by using the Lie classical symmetry method. The obtained solutions are in terms of trigonometric functions and hyperbolic functions. This equation can ...
Invariance analysis, exact solution and conservation laws of (2 + 1) dim fractional kadomtsev-petviashvili (kp) system
(MDPI AG, 2021-03-16)
In this work, a Lie group reduction for a (2 + 1) dimensional fractional Kadomtsev-Petviashvili (KP) system is determined by using the Lie symmetry method with Riemann Liouville derivative. After reducing the system into ...
Space-Time Fractional KdV�Burger�Kuramato Equation with Time Dependent Variable Coefficients: Lie Symmetry, Explicit Power Series Solution, Convergence Analysis and Conservation Laws
(Springer, 2022-02-21)
In this paper, Lie symmetry reduction, power series solutions, convergence analysis and conservation laws have been examined for the space-time fractional KdV�Burger�Kuramato equation with time dependent variable coefficients. ...
Generalised Two-Component Modified Weakly Dissipative Dullin-Gottwald-Holm System: Invariance Analysis and Conservation Laws
(VGTU, 2022-02-07)
The Dullin-Gottwald-Holm equation models the unidirectional propagation of shallow regime water waves. In this work, the Lie symmetry analysis of the generalised two-component modified weakly dissipative Dullin-Gottwald-Holm ...
Invariant Bianchi type I cosmological models and conservation laws in f(R,T)=f1(R)+f2(R)f3(T) gravity
(Elsevier B.V., 2023-05-12)
f(R,T) theory of gravity can explain the dark energy and the observed late time acceleration of the universe even without cosmological constant. It passes the solar system test and appears to be an alternative of dark ...
Invariance properties, conservation laws, and soliton solutions of the time-fractional (2 + 1) -dimensional new coupled ZK system in magnetized dusty plasmas
(Springer Science and Business Media, LLC, 2018)
This paper investigates time-fractional (2+1)-dimensional new coupled Zakharov–Kuznetsov system for the invariance properties, conservation laws, and soliton solutions. Lie infinitesimal symmetries and corresponding ...
