| 16. | Shota Shigetomi and Kenji Kajiwara, Explicit formulas for motions of smooth/discrete elasticae, Australia New Zealand Industrial and Applied Mathematics Conference 2021, 2021.02, Elastica is known as the shape of a thin elastic rod on the plane. Mathematically, it is characterised by the differential equation for its curvature. It is also known that traveling wave solutions of the modified KdV equation satisfy the equation for Elastica. Thanks to its integrability, it is possible to construct a discrete version of Elastica characterised by the integrable discrete analog of the modified KdV equation. We construct explicit solutions to the motion of Elastica described by the modified KdV equation. We also construct the explicit solutions to continuous and discrete motions of the discrete Elastica described by the semi-discrete potential modified KdV equation and the discrete potential modified KdV equation, respectively. Explicit formulas in terms of the tau function are presented.. |
