Comment on "Three papers published by Subhas Abel and his co-workers in International Journal of Non-Linear Mechanics and International Journal of Thermal Sciences

The above paper concerns the boundary layer flow of a visco-elastic fluid along a stretching sheet immersed in a porous medium. The plate temperature is different from that of the ambient medium and the fluid viscosity is a function of temperature while the other fluid properties are assumed to be constant. The boundary layer equations are transformed into ordinary ones and subsequently are solved using the shooting method with Runge-Kutta integration algorithm. However, there are two fundamental errors in this paper which are presented below.
