  We investigated the analytical solution of fractional order K(m,n) type
equation with variable coefficient which is an extended type of KdV equations
into a genuinely nonlinear dispersion regime. By using the Lie symmetry
analysis, we obtain the Lie point symmetries for this type of time-fractional
partial differential equations (PDE). Also we present the corresponding reduced
fractional differential equations (FDEs) corresponding to the time-fractional
K(m,n) type equation.
