Multiple types of exact solutions and conservation laws of new coupled (2 + 1) -dimensional Zakharov–Kuznetsov system with time-dependent coefficients
(Springer, 2019)
This paper investigates the new coupled (2 + 1) -dimensional Zakharov–Kuznetsov (ZK) system with time-dependent coefficients for multiple types of exact solutions by using the Lie symmetry transformation method. Similarity ...
On new symmetries and exact solutions of Einstein�s field equation for perfect fluid distribution
(Springer, 2021-07-27)
Some new infinite-dimensional generalised Lie symmetries of Einstein�s field equations for perfect fluid distribution are found by using the Lie symmetry analysis. The reduced ordinary differential equations are solved to ...
