MHD stagnation-point flow over a stretching/shrinking sheet in a micropolar fluid with a slip boundary

The problem of stagnation point flow over a stretching/shrinking sheet immersed in a micropolar fluid is analyzed numerically. The governing partial differential equations are transformed into a system of ordinary (similarity) differential equation and are then solved numerically using the boundary...
