Rigidity in hyperbolic Dehn filling
Ian Agol, BoGwang Jeon
This paper concerns with a rigidity of core geodesics in hyperbolic Dehn fillings. For instance, for an -cusped hyperbolic -manifold having non-symmetric cusp shapes, we…

Embedding Heegaard Decompositions
Ian Agol, Michael H. Freedman
A smooth embedding of a closed -manifold in may generically be composed with projection to the fourth coordinate to determine a Morse function on and henc…
