English abstract

In this paper, we have tried to find the pattern of change of keywords of an arbitrary science subject with its age. The mode of temporal evolution of a subject is formulated on the basis of some fundamental assumptions. It has been mathematically derived that the number of keywords of a subject will always tend to attain a saturation value with the age of the subject. The other interesting feature is that, when a subject gets overloaded with keywords, then it tries to share the same with some peripheral subject areas and consequently new subjects are formed.
