Some Limit Properties of Populations Modeled by Verhulst Equation

چکیده مقاله

Those who have studied the population size, i.e., the demographers, are eager to build a real model which not only describe the demographic changes in the past periods, but can predict these changes in coming periods. They are very eager to find what factors are effective in the population size, and which of these factors can be controlled by social policies? These are difficult questions. The prediction of Verhulst law about great bunch of populations has been correct. In this study, we are going to show that the populations modeled by Verhulst equation are not a limit of a sequence of a cyclic generations
