On hyperbolic 3-manifolds obtained by Dehn surgery on links.
An irreducible Heegaard diagram of the real projective 3-space .
-curves inducing two different knots with the same -fold branched covering spaces
For a knot with a strong inversion induced by an unknotting tunnel, we have a double covering projection branched over a trivial knot , where is the axis of . Then a set is called a -curve. We construct -curves and the cyclic branched coverings over -curves, having two non-isotopic Heegaard decompositions which are one stable equivalent.
