Abstract

The purpose of this paper is to introduce various nonnegative systems and preset the stability analysis method of each system. Biological phenomena are modeled using nonnegative conditions such as the number of animals, the concentration of chemicals in the body. Nonnegative systems represent not only biological and biological phenomena but also various phenomena. This paper introduces various nonnegative systems such as nonnegative linear system, Lotka-Volterra equation, positive secondary system, and so on. In addition, this paper clarifies the range of phenomena that each nonnegative system can express. Finally, this paper introduces the stability analysis method peculiar to the nonnegative system.
