Finsler geometry is a metric generalization of Riemannian geometry and constitutes a comparatively young branch of differential geometry. The germs of Finsler geometry were present in the epoc-making lecture of B. Riemann at Gottingen University in 1854. Finsler geometry has wide applications in the fields of Physics and Biology such as Thermodynamics, Optics, Relativity, Cosmology, Ecology and developmental Biology.
