Abstract:

Let f be a meromorphic function of finite positive order in the unit circle and F be a differential polynomial in f, If the order of growth of F is same as that of f, then the Borel points of F must be the Borel points of f. In particular the Borel points of a monomial in f are also the Borel points of f under certain conditions. In addition, A result on orders of homogeneous differential polynomial due to Singh,A.P.is generalized.
