Constructing Stein exotic 4-manifolds

We explain some 4-dimensional handlebody technics which allows us to understand surgeries and construct new manifolds from the old one. The particular construction we demonstrate during the talk uses "roping", "corks", and "anticorcks" to construct exotic contractible Stein manifold pairs, as well as exotic homotopy $S^1\times B^3$ pairs, which are Stein. This is joint work with Selman Akbulut.
