Order 2 Algebraically Slice Knots
The concordance group of algebraically slice knots is the subgroup of
the classical knot concordance group formed by algebraically slice
knots. Results of Casson and Gordon and of Jiang showed that this
group contains in infinitely generated free (abelian) subgroup. Here
it is shown that the concordance group of algebraically slice knots
also contain elements of finite order; in fact it contains an infinite
subgroup generated by elements of order 2.
