“…The influence of Hall current on the rotating oscillating flows of an Oldroyd-B fluid in a porous medium has been studied by Hayat et al (2007). In few other investigations (Katagiri, 1962;Jana et al, 1977;Gosh, 1993Gosh, , 1999 have discussed the MHD flow under different physical aspects, whereas, Mandal and Mandal (1983) and Jha and Apere (2010) have studied the effect of Hall currents under varying conditions. To the best of our knowledge, the effect of slip condition with Hall current on the magnetohydrodynamic flow of a rotating viscous fluid in a porous medium bounded by a porous plate has not been discussed in the literature of rotating flows.…”
