| Popis: | We show that there are no distance one surgeries on non-null-homologous knots in $M$ that yield $-M$ ($M$ with opposite orientation) if $M$ is a 3-manifold obtained by a Dehn surgery on a knot $K$ in $S^{3}$, such that the order of its first homology is divisible by $9$ but is not divisible by $27$. As an application, we show several knots, including the $(2,9)$ torus knot, do not have chirally cosmetic bandings. This simplifies a proof of the result first proven by Yang; the $(2,k)$ torus knot $(k>1)$ has a chirally cosmetic banding if and only if $k=5$. Comment: 4 pages, no figure |
