Abstract
The author [1] studied the effects of thermal radiation , variable viscosity and heat generation on the on boundary layer flow and heat transfer over an exponentially stretching porous sheet with constant heat flux . The physical quantities of interest in the boundary layer flow and heat transfer studies are the local skin-friction coefficient and the surface heat flux. Unfortunately, there are fundamental errors in the definitions of these quantities in the above paper [1] :
