Lie symmetry classification and invariant solutions of time-fractional telegraph systems with variable coefficients
Lie symmetry classification of time-fractional telegraph systems with variable coefficients identifies three symmetry classes depending on the relation between transport coefficient and potential, and produces exact invariant solutions in Mittag-Leffler, generalized Wright, and Fox H-functions.
