Abstract
There are real life situations in our lives where the things are
changing continuously or from time to time. It is a very important
problem for one whether to continue the existing relationship or to form
a new one after some occasions. That is, people, companies, cities,
countries, etc. may change their opinion or position rapidly. In this
work, we think of the problem of changing relationships from a
mathematical point of view and think of an answer. In some sense, we
comment these changes as power changes. Our number theoretical model
will be based on this idea. Using the convolution sum of the restricted
divisor function $E$, we obtain the answer to this problem.
