Comment on `Oblique Propagation and Dissipation of Alfvén Waves in Coronal Holes' by Srivastava and Dwivedi

Abstract

We comment on the recent paper by Srivastava and Dwivedi (J. Astrophs. Astr. {\bf 28}, 1, 2007). In the said paper the derived dispersion relation $\nu \eta {\cos }^4\theta k^4+[v_A^2-i\omega (\nu +\eta )]{\cos }^2\theta k^2-{\omega }^2=0$ seems to be in error. Consequently, the conclusion drawn in their paper are not reliable.
