Item Removal of phosphate from aqueous medium by dolomite-potential method for treatment of industrial effluents(University of Perdeniya. Peradeniya, 1999) Perera, S.; Priyantha, N.Item Support points of subordination families(University of Peradeniya. Peradeniya, 1995) Perera, S.A general theorem for support points of subordination families is proved. This theorem provides a unified approach to the support points of the families subordinate to starlike functions. Close-to-convex functions of order ß(=1) and functions having boundary rotation at most kπ(K>2). The results for starlike functions and close-to-convex functions were previously known by different methods.
