Densities in free groups and $Z^{k}$ , Visible Points and Test Elements

Ilya Kapovich, Igor Rivin, Paul Schupp +1

In this article we relate two different densities. Let $F_{k}$ be the free group of finite rank $k \geq 2$ and let $α$ be the abelianization map from $F_{k}$ onto $Z^{k}$ . We pr…

A property of alternating groups

Henry Cejtin, Igor Rivin

We describe an efficient algorithm to write any element of the alternating group A_n as a product of two n-cycles (in particular, we show that any element of A_n can be so written…

A Remark on "Counting primitive elements in free groups" (by J. Burillo and E. Ventura)

Igor Rivin

We observe that a sharp result on the exponential growth rate of the number of primitive elements exists for the free group on two generators.
