A mathematical model for nordic skiing (Ein mathematisches Modell für den nordischen Skisport)
MacDonald, J. S., Cardales, R. O., Stockie, J. M.Veröffentlicht in arXiv e-print repository (2024)“… Nordic skiing provides fascinating opportunities for mathematical modelling studies that exploit methods and insights from physics, applied mathematics, data analysis, scientific computing and sports science. A typical ski course winds over varied terrain with frequent changes in elevation and direction, and so its geometry is naturally described by a three-dimensional space curve. …”
