Contribution
It introduces a classification of rational elements with specific poles in a real twisted loop group and applies dressing actions to produce new affine sphere examples.
Findings
Classification of rational elements with 3 or 6 poles
Explicit computation of dressing actions on affine spheres
Generation of new affine sphere examples with visualizations
Abstract
We will first clarify the loop group formulations for both hyperbolic and elliptic definite affine spheres in R^3. Then we classify the rational elements with 3 poles or 6 poles in a real twisted loop group, and compute dressing actions of them on such surfaces. Some new examples with pictures will be produced at last.
