    • A Family Of Nonramified Functions, Defined In Zz<1 

      Gabr, M. K [محمد كامل جبر] ( Qatar University , 1983 , Article)
      In this article a family of nonramified functtions, defined in zz<l, is obtained. It is characterized by an achieved distortion theorem; its Bloch constant and the limit of convexity are determined. Peschl's principle is. ...

    • Generalized Airy's- and taylor Integral Functions 

      Gabr, M. K [محمد كامل جبر]; Shalem, Sh. ( Qatar University , 1982 , Article)
      In this paper a generalized form of Airy's function has been estimated and an asymptotic expansion for one of its types is obtained. Furthermore, an improved formula could be induced to acquire the asymptotic expansion of ...

    • On The Behaviour Of The Solutions Of ff …... 

      Gabr, M. K [محمد كامل جبر]; Salem, S. H. ( Qatar University , 1984 , Article)
      The above equation plays an important rote in the geometric theory of functions of a complex variable. To determine interval estimations for its solutions, an inequality is obtained using the fixed point theorem. Then, ...
