Algebraic Closed Geodesics on a Triaxial Ellipsoid | Yuri Fedorov
; | Date: |
29 Jun 2005 | Abstract: | We propose a simple method of explicit description of families of closed geodesics on a triaxial ellipsoid $Q$ that are cut out by algebraic surfaces in ${mathbb R}^3$. Such geodesics are either connected components of spatial elliptic curves or rational curves. Our approach is based on elements of the Weierstrass--Poncaré reduction theory for hyperelliptic tangential covers of elliptic curves and the addition law for elliptic functions. For the case of 3-fold and 4-fold coverings, explicit formulas for the cutting algebraic surfaces are provided and some properties of the corresponding geodesics are discussed. | Source: | arXiv, nlin.SI/0506063 | Services: | Forum | Review | PDF | Favorites |
