Finsler geometry is a subject that concerns manifolds with Finsler metrics including Riemannian metrics. It has applications in many fields of natural sciences such as Biology, Econometrics, Physics etc. This invaluable book presents some advanced work done by the author in Finsler and Lagrange Geometry such as the theory of hyper surfaces with a beta change of Finsler metric, Cartan spaces with Generalized (, )-metric admitting h-metrical d-connection.In addition to above topics, four dimensional Finsler space with constant unified main scalars, conformal change of four dimensional Finsler...
