Generic immersions and totally real embeddings
Naohiko Kasuya, Masamichi Takase
We show that, for a closed orientable n-manifold, with n not congruent to 3 modulo 4, the existence of a CR-regular embedding into complex (n-1)-space ensures the existence of a to…
Knots and links of complex tangents
Naohiko Kasuya, Masamichi Takase
It is shown that every knot or link is the set of complex tangents of a 3-sphere smoothly embedded in the three-dimensional complex space. We show in fact that a one-dimensional su…
Regular-equivalence of -knot diagrams and sphere eversions
Masamichi Takase, Kokoro Tanaka
For each diagram of a -knot, we provide a way to construct a new diagram of the same knot such that any sequence of Roseman moves between and necessarily invol…
On a move reducing the genus of a knot diagram
Kenji Daikoku, Keiichi Sakai, Masamichi Takase
For a knot diagram we introduce an operation which does not increase the genus of the diagram and does not change its representing knot type. We also describe a condition for this…
