Abstract |
|
|
| This paper addresses the Sharma-Tasso-Olver equation from an integrability perspective. There are three integration tools
that are applied to extract the solutions to this nonlinear evolution equation. The ansatz method is applied to the generalised equation
with power-law nonlinearity to obtain shock-wave solutions. Subsequently, the traveling-wave hypothesis leads to another set of
solutions in the complex domain. Finally, Lie symmetry analysis leads to a third set of solutions. Several constraint conditions emerge
from the various analyses. |
