Extensions of immersions of surfaces into $R^{3}$

Bojun Zhao

This paper is to study the $R^{3}$ case of \hyperref[Zhao]{[9]}. We determine all equivalence classes of immersed $3$ -manifolds bounded by an arbitrary immersed surface in…

The extending surfaces of immersions into surfaces

Bojun Zhao

S. Blank solved the question of classifying immersed circles in $R^{2}$ that extend to immersed disks, and how many topologically inequivalent disks can be extended. The q…
