By applying the Lie group symmetry method, we determine all symmetries for these equations and present the reduced symmetric equations for the equation K(m,n) with fractional Caputo time derivatives. Furthermore, we obtain the exact solution for K(1,1) with the fractional Caputo time derivative and provide graphs depicting the behavior at different orders of the fractional time derivative. Additionally, by considering the symmetries of the equation, we establish the conservation laws for K(m,m) with the fractional Caputo time derivative.eninfo:eu-repo/semantics/openAccessLie GroupsConservation LawsFractional CalculusNonlinear Differential EquationsArticle423885899N/A2-s2.0-8520063123510.14744/sigma.2024.00078
