Abstract

‎In this paper‎, ‎the geometric method of symmetry is used to study the full extended Korteweg-de Vries equation‎: ‎$u_t+6uu_x+u_{xxx}+a_1 u^2u_x+a_2 uu_{xxx}+a_3 u_xu_{xx}+a_4 u_{xxxxx}=0$‎. ‎Based on the different states of the $a_i$~s parameters‎, ‎the problem is divided into different branches‎. ‎While carefully examining each of these cases‎, ‎the geometric properties of the set of solutions are studied and specific solutions are obtained for different cases‎.
