The phrase "prime period" is correct and can be used in written English.
It refers to a period of time that is considered the most important or influential. Example: The company's prime period for sales is during the holiday season.
Each d ∈ D is either a periodic element with an even prime period or an eventually periodic element that leads to a periodic element whose prime period is even.
(ii) Each d ∈ D is either a periodic element with an even prime period or an eventually periodic element that leads to a periodic element whose prime period is even. .
Mainly, the lengths of positive and negative semicycles of its nontrivial solutions are found to occur periodically with prime period 15.
We say that the solution is periodic with prime period p if p is the smallest positive integer for which (2) holds.
In this paper, it is of key for us to find that the lengths of positive and negative semi-cycles of nontrivial solutions of (1.1) occur periodically with prime period 15 with the rule,,,,,,, and in a period.
(ii) Each d ∈ D is either a periodic element or an eventually periodic element whose prime period is odd. .
Each d ∈ D is either a periodic element or an eventually periodic element whose prime period is odd.
Then (1.4) has a periodic solution of prime period two.
The following theorem states the necessary and sufficient conditions that this equation has periodic solutions of prime period two.
Then, the lengths of positive and negative semi-cycles of the solution periodically successively occur with prime period 15.
nonoscillatory and eventually negative (i.e., ) or. strictly oscillatory with the lengths of positive and negative semi-cycles periodically successively occurring with prime period 15 and the rule to be,,,,,,, in a period.
