Item Comment on “Lie symmetries and group classification of a class of time fractional evolution systems” [J. Math. Phys. 56, 123504 (2015)](Springer, 2017) Singla, Komal; Gupta, R. K.In this article, the prolongation formulae proposed in Huang and Shen [J. Math. Phys. 56, 123504 (2015)] for the analysis of time fractional systems of are proved incomplete and the required correct prolongation operators are suggested. With the help of some examples, the efficiency of the operators introduced in this study is illustrated.Item Space–time fractional nonlinear partial differential equations: symmetry analysis and conservation laws(Springer, 2017) Singla, Komal; Gupta, R. K.The symmetry method is developed to study space–time fractional nonlinear partial differential equations. Also, the Noether operators are extended for determining the conservation laws by application to some physically significant space–time fractional nonlinear partial differential equations.
