In this work, we investigate invariance analysis, conservation laws, and exact power series solutions of time fractional generalized Drinfeld–Sokolov systems (GDSS) using Lie group analysis. Using point symmetries the Erdelyi–Kober (EK) differential operator, GDSS equation is reduced to a nonlinear ordinary (ODE) order. Moreover, have constructed laws for obtained explicit ODEs that converge. L...
