| Outline of Final Research Achievements |
The initial-value problem for the equations of Kirchhoff elastic rods in complete Riemannian manifolds was studied, and it was proven that there exists a unique global solution of this initial-value problem. Also, a class of fourth soliton curves in three-dimensional Euclidean space was explicitly expressed in terms of Jacobi elliptic functions, and it was proven that there exist periodic solutions in this class. Each periodic solution winds around a torus of revolution. By using these periodic fourth soliton curves, congruence solutions (solutions moving without change of shape) of the "space curve version of the modified KdV equation" were constructed.
