Abstract:

Under the relation of $0$-concordance, the set of knotted 2-spheres in $S^4$ forms a commutative monoid $\mathcal {M}_0$ with the operation of connected sum. Sunukjian [Int. Math. Res. Not. IMRN 17 (2015), pp. 7950–7978] has recently shown that $\mathcal {M}_0$ contains a submonoid isomorphic to $\mathbb {Z}^{\ge 0}$. In this note, we show that $\mathcal {M}_0$ contains a submonoid isomorphic to $(\mathbb {Z}^{\ge 0})^\infty$. Our argument relates the $0$-concordance monoid to linear independence of certain Seifert solids in the spin rational homology cobordism group.
