ABSTRACT
In the study of surfaces in 3-manifolds, the so-called “cut-and-paste” of surfaces
is frequently used. In this paper, we generalize this method, in a sense,
to singular-surfaces, and as an application, we prove that two collections
of singular-disks in the 3-space
which span the same trivial link are
link-homotopic in the upper-half 4-space
keeping the link fixed.
Throughout the paper, we work in the piecewise linear category, consisting of simplicial complexes and piecewise linear maps.
