Double stratified MHD stagnation point slip flow over a permeable shrinking/stretching surface in a porous medium

The intention of this article is to investigate the impact of slip of MHD stagnation point flow over a permeable shrinking/stretching sheet with double stratification in a porous medium. Employing the appropriate similarity transformations and non-dimensional variables, the governing partial differe...
