Dynamical behavior of similarity solutions of CKOEs with conservation law

作者:

Highlights:

• System of coupled Konno–Oono equations (CKOEs) describes the propagation of a current-fed string in 3-dimensional space interacting with an external magnetic field.

• Optimal subalgebra and invariants for the CKOEs are generated with the help of killing form.

• Using the Noether’s theorem, the conserved vectors are calculated to show strong indication of integrability of the CKOEs.

• Exact solutions show physical behaviors like single soliton, doubly soliton, bright and dark multisolitos, stationary, traveling wave, asymptotic and highly progressive.

• One, two and three dimensional optimal subalgebra generated for the CKOEs.
