Comment on `Oblique Propagation and Dissipation of Alfvén Waves in Coronal Holes' by Srivastava and Dwivedi
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 $νη\cos^4 θk^4 + [v_A^2 - i ω(ν+ η)] \cos^2 θk^2 - ω^2 = 0$ seems to be in error. Consequently, the conclusion drawn in their paper are not reliable.
