| Outline of Final Research Achievements |
In affine algebraic geometry, affine space is the most fundamental and important object. However, we have not obtained the algebro-geometric characterization of affine space of higher dimension. In this project, trying to provide characterizations of affine spaces among algebraic varieties, we investigated the additive group actions on algebraic varieties of three or higher dimension, and succeeded in determining the structure of three-dimensional algebraic varieties in some cases.
