ABSTRACT

Dwivedi and Srivastava [1] (DS) investigated the propagation and dissipation of Alfvén waves in coronal holes after accounting for the viscosity and magnetic diffusivity. After solving a set of equations with the help of computer results are reported by them. We find that the same set of equations can be solved even analytically. Since DS have not reported any values of physical parameters used by them except their expressions, we could not trace out the source of error. One reason for the difference in our results and those of DS can be assigned to some mistakes in their computer program or to the values of parameters used.
