In a recent paper, one of the main focal points is the robustness of positive property for a k-variate interval rational function having complex coefficients (hereafter the property is referred to as PC property). It is concluded that the PC property of the specific 16(2fc)“extreme members of the set can imply the PC property of the set. In this note, it is proven that the PC property of a k-variate complex interval rational function can be assured by the PC property of its certain 16 (2A) extreme members which are a proper subset of those 16 (2A) extreme members defined in the above-mentioned paper1.
