| Outline of Final Research Achievements |
We made computational approaches to various arithmetic-geometric objects related to finite ordered points on elliptic curves and/or Jacobian varieties, including periodic continued fractional expansions about specific polynomial Pell equations, algebraic deformation of Poncelet polygons, Diophantine equations related to arithmetic of elliptic curves. Using intersections of cevians of plane triangles, we obtained basic properties of certain triangle operations with two complex variables together with visual outputs of iteration of area preserving operators.
