*Distinct Stein structures on contractible 4-manifolds*
Stein manifolds are special compact subsets of affine algebraic varieties
which play an important role in complex/symplectic geometry and singularity
theory. Due to Eliashberg's topological characterization, the existence and
uniqueness of Stein structures on n-dimensional manifolds are
well-understood for n>4, but are more challenging when n=4. I will give a
brief survey on these problems and talk about a recent construction done
in collaboration with Oba and Ukida.
