Abstract

In a recent paper by Bose and Dalansky [ll Dasguata's result [10] has been extended to study the robustness of positive complex (PC) rational and strictly positive complex (SPC) rational properties for a complex interval rational function. It is concluded that the PC (SPC) property of the specific 64 extreme members of the set can imply the PC (SPC) property of the set. In this paper, it is proven that the PC (SPC) property of a complex interval rational function can be guaranteed by the PC (SPC) property of its certain 32 extreme members, which are a subset of those 64 extreme members defined in [11].
