This study investigates the nonlinear Pochhammer–Chree equation, a model crucial for understanding wave propagation in elastic rods, through the application of the Khater III method. The research aims ...
where \(\Phi =\Phi (t,x,y,z)\) represents an unknown function. This KdV-type equation is commonly used mathematically to describe ion acoustic waves in plasma, shallow water wave equations, and ...
