On the periods of a periodic function
International Journal of Mathematical Education in Science and Technology, 2005It is known that any nonconstant real-valued periodic function defined on the set of all real numbers is either discontinuous at each point of its domain or has a least positive period. Using the additive semigroup consisting of non-negative periods, we generalize this result by giving a unified proof of the same conclusion when the domain of the given

Periodicity and Almost-Periodicity
2006Periodicity and almost-periodicity are phenomena which play an important role in most branches of mathematics and in many other sciences. This is a survey paper1 on my work in this area and on related work. I restrict myself to periodicity questions in combinatorics on words (the main dish), but I start with a periodicity problem from number theory ...
