Non-orientable genus of knots in punctured Spin 4-manifolds

Kouki Sato

For a closed 4-manifold $X$ and a knot $K$ in the boundary of punctured $X$ , we define $γ_{X}^{0} (K)$ to be the smallest first Betti number of non-orientable and null-homologous surfac…

Non-orientable genus of a knot in punctured $C P^{2}$

Kouki Sato, Motoo Tange

For any knot $K$ which bounds non-orientable and null-homologous surfaces $F$ in punctured $n C P^{2}$ , we construct a lower bound of the first Betti number of $F$ which consi…
