Dehn surgery on knots in $S^{3}$ producing Nil Seifert fibred spaces

Yi Ni, Xingru Zhang

We prove that there are exactly $6$ Nil Seifert fibred spaces which can be obtained by Dehn surgeries on non-trefoil knots in $S^{3}$ , with ${60, 144, 156, 288, 300}$ as the exact…

Thurston norm and cosmetic surgeries

Yi Ni

Two Dehn surgeries on a knot are called cosmetic if they yield homeomorphic manifolds. For a null-homologous knot with certain conditions on the Thurston norm of the ambient manifo…
