In the case of Apple increasing the price for iPhones, this would reduce sales of iPhones and the demand for iOS apps. In complementarity theory, which is a relatively new domain of applied mathematics, several kinds of mathematical models and problems related to the study of equilibrium are considered from the point of view of physics as well as economics.
