%0 Journal Article %T A merry-go-round with the circle map, primes and pseudoprimes %A M. Leo %A R. A. Leo %A G. Soliani %J Mathematics %D 1999 %I arXiv %X We show that the use of the main characteristics of the circle map leads naturally to establish a few statements on primes and pseudoprimes. In this way a Fermat's theorem on primes and some interesting properties of pseudoprimes are obtained. %U http://arxiv.org/abs/math/9912079v1
