| Research Abstract |
Research on vector fields on affine varieties and properties of A^1-fibrations and A^1_*-fibrations on affine threefolds was successfully conducted. Properties of singular points on affine normal surfaces are also explored. Through this research, a new scope of studying the structure of affine threefolds via deformation theory is envisioned.
