Comments on ‘‘Numerical solutions of the space- and time-fractional coupled Burgers equations by generalized differential transform method, Applied Mathematics and Computation 217 (2011) 7001–7008’’

In a paper by Liu and Hou (2011) [1] the fractional coupled Burgers equation is solved by gen- eralized two dimensional differential transform method. Two examples are solved in the above paper. The presented solution is true only for a special case, while the authors claim that their solutions generally are correct. In this paper, we present the true solution of the problems.
